30,380,054 | 0 | How do I iterate through a string contained in a vector? <p>For clarity, I am not asking how to iterate through a vector of strings (which is what all of my searches turn up), I want to iterate through a string contained in a vector of strings. I'm running into linker errors when trying to assign the string iterator a value from a string in a vector. </p> <p>The code below takes a reference to a const vector of strings. The purpose of the function is to reverse the order of the letters and the elements so if you passed in a vector of strings containing { "abc", "def", "ghi" } it would reorder them and return a vector of strings containing { "ihg", "fed", "cba" }. It should be noted that the function is declared as static in the header file. I'm running into a problem when I try to attempt to initialize the string iterator in the for loop. I get a linker error:</p> <pre><code>"No matching constructor for initialization of 'std::__1::__wrap_iter<char*>' </code></pre> <p>I thought accessing rbegin() through the -> from the vector iterator would work but... I'm stumped. Why does stringsVectorIterator->rend() cause a linker error when assigned to string::reverse_iterator rit?</p> <pre><code>vector<string> StringUtility::reverse(const vector<string> &strings) { // Create a vector of strings with the same size vector as the one being passed in. vector<string> returnValue( strings.size() ); vector<string>::const_reverse_iterator stringsVectorIterator; size_t returnVectorCounter; for (stringsVectorIterator = strings.rbegin(), returnVectorCounter = 0; stringsVectorIterator != strings.rend(); stringsVectorIterator++, returnVectorCounter++) { // the problem is in the initialization of the string iterator, it creates // a linker error. for (string::reverse_iterator rit = stringsVectorIterator->rbegin(); rit != stringsVectorIterator->rend(); ++rit) { returnValue[returnVectorCounter].push_back(*rit); } } return returnValue; }; </code></pre> |

14,842,936 | 0 | regular expression to exclude a specific string <p>I am currently implementing an identity management solution that will provide users the ability to manage all of their endpoint accounts.</p> <p>Currently, our company password policy matches the default Windows requirements: must contain either a number or a special character, among others.</p> <p>Unfortunately, in the new system's password policy, we can require a number, a special, or both, but not "one of either." However, the new system allows validation by regular expression.</p> <p>Currently, we have this set to DISALLOW the following regex:</p> <pre><code>.*[pP][aA4][sS$]{2}[wW][oO0][rR][dD].* </code></pre> <p>This works pretty well. However, we would like to change this to ALLOW either a digit or a special, while also DISALLOWING the previous.

The digit/special group works fine, however the word group does not. It does see if "password" or some variation is used at the END of the string, but not at the beginning...</p> <p>Any suggestions?

If you really wanted to do the bare-bones amount of work necessary to build an internationalized application,is the only action that you'll need to consider. The action takes advantage of the LocalizationContext (which we talk about in the next section).By using the ,you can output values from your resource bundles as simply as:</p> <pre><code><fmt:message key="welcome"/> </code></pre> <p>The appropriate resource bundle will be used to look up the key "welcome" and the translated string will be provided. This is about as easy as it gets to incorporate international support into your application. The action also supports parameterized content, also called parametric replacement. For example, you can provide variables that will be used within the string used by the key attribute. Say we want to personalize our welcome page and pass the name of a user so that we can welcome them. To do this, we use the <code><fmt:param></code> subtag. We will talk about this in more detail later in this chapter, but as a quick example, so that you are familiar with the format, the action might look like:</p> <pre><code><fmt:message key="welcome"> <fmt:param value="${userNameString}"/> </fmt:message> </code></pre> <p>taken from <a href="http://www.javaranch.com/journal/2003/09/AnIntroductionToJstl.html" rel="nofollow">here</a></p> |

6,680,595 | 0 | Java SQL Escape without using setString <p>Is there a built-in method to escape a string for SQL? I would use setString, but it happens I am using setString multiple times in the same combined SQL statement and it would be better performance (I think) if the escape happened only once instead of each time I say setString. If I had the escaped string in a variable, I could re-use it.</p> <p>Is there no way to do this in Java?</p> <p>Current method, multi-source search. In reality they are three entirely different where statements including joins, but for this example I will just show the same where for each table.</p> <pre><code>String q = '%' + request.getParameter("search") + '%'; PreparedStatement s = s("SELECT a,b,c FROM table1 where a = ? UNION select a,b,c from table2 where a = ?

27,402,446 | 0 | <blockquote> <p>I think what I do here is considered to be bad practice, isn't it?</p> </blockquote> <p>Yes, exposing mutable portions of your class through a getter may be misleading, because the data is not encapsulated well enough. There is nothing wrong with changing the data, it's just that it is done in a way that does not immediately stand out as modification.</p> <p>There is no universal rule to fix this. Generally, you should avoid returning mutable objects inside your class directly. Instead, provide getters and setters where appropriate, and do not give <code>List<B></code> to your caller:</p> <pre><code>class A { private List<B> bs = new ArrayList<B>; public void getSizeB() { return bs.size(); } public B getB(int i) { return bs.get(i); } public void setB(int i, B b) { bs.set(i, b); } public void addB(B b) { bs.add(B); } ... // Add more methods as needed } </code></pre> <p>The idea is to stay in control of what gets into your <code>List<B></code>: since there is no direct access, you can validate every <code>B</code> that gets into the list. The code that uses your class <code>A</code> must be explicit about all modifications that it makes, because it cannot get the list directly and do whatever it wants with it.</p> |

You can, of course, develop your own style, but it develops, it isn't just given to you. Knowing the messes you can get into helps you develop style (technique) in avoiding getting there. You'll still need to know how things happen, because not all programmers take the time to develop anything in the way of style.</p> <p>Read through some of the questions here, and see if you get some ideas about common problems.</p> |
33,113,171 | 0 | <p>I think you are confusing assigning variables with aliases. assigning a variable means you store the result of the command in a variable what this command does</p> <pre><code>b=`pwd` </code></pre> <p>is running <code>pwd</code> and stores the answer in a variable b.</p> <p>and alias means giving some command a different name. so running <code>alias b pwd</code> will make it so whenever you run b, you will actually run <code>pwd</code></p> |
6,223,689 | 0 | <p>The keyword <code>static</code> unfortunately has a few different unrelated meanings in C++</p> <ol> <li><p>When used for data members it means that the data is <strong>allocated in the class</strong> and not in instances.</p></li> <li><p>When used for data inside a function it means that the data is allocated statically, <strong>initialized the first time the block is entered</strong> and lasts until the program quits. Also the variable is visible only inside the function. This special feature of local statics is often used to implement lazy construction of singletons.</p></li> <li><p>When used at a compilation unit level (module) it means that the variable is like a global (i.e. allocated and initialized before <code>main</code> is run and destroyed after <code>main</code> exits) but that <strong>the variable will not be accessible or visible in other compilation units</strong>.</p></li> </ol> <p>I added some emphasis on the part that is most important for each use. Use (3) is somewhat discouraged in favor of unnamed namespaces that also allows for un-exported class declarations.</p> <p>In your code the <code>static</code> keyword is used with the meaning number 2 and has nothing to do with classes or instances... it's a variable of the <strong>function</strong> and there will be only one copy of it.</p> <p>As correctly <strong>iammilind</strong> said however there could have been multiple instances of that variable if the function was a template function (because in that case indeed the function itself can be present in many different copies in the program). Even in that case of course classes and instances are irrelevant... see following example:</p> <pre><code>#include <stdio.h> template<int num> void bar() { static int baz; printf("bar<%i>::baz = %i\n", num, baz++); } int main() { bar<1>(); // Output will be 0 bar<2>(); // Output will be 0 bar<3>(); // Output will be 0 bar<1>(); // Output will be 1 bar<2>(); // Output will be 1 bar<3>(); // Output will be 1 bar<1>(); // Output will be 2 bar<2>(); // Output will be 2 bar<3>(); // Output will be 2 return 0; } </code></pre> |

17,164,641 | 0 | <p>The best way to do this would be to use <code>grep</code> to get the lines, and populate an array with the result using newline as the internal field separator:</p> <pre><code>#!/bin/bash # get just the desired lines results=$(grep "mypattern" mysourcefile.txt) # change the internal field separator to be a newline IFS=$'/n' # populate an array from the result lines lines=($results) # return the third result echo "${lines[2]}" </code></pre> <p>You could build a loop to iterate through the results of the array, but a more traditional and simple solution would just be to use bash's iteration:</p> <pre><code>for line in $lines; do echo "$line" done </code></pre> |

26,947,543 | 0 | <p>Yes, this is correct. In your example <code>%PATH%</code> will be expanded to the current value of the PATH variable, so this command is effectively adding a new entry to the beginning of the PATH. </p> <p>Note that calling <code>set PATH</code> will only affect the current shell. If you want to make this change permanent for all shells, the simplest option is to set it as a user variable using the Environment Variables dialog box. </p> <p>On Windows 8 you can open this dialog by hitting Win+s and searching for 'environment variables'. On earlier versions of Windows you can right-click 'My Computer', choose Properties, then Advanced system settings, then Environment variables. You can create (or update) a PATH variable in the user variables section and add whatever entries you need. These will be appended to the existing system path. If you take this approach you will need to open a new cmd shell after updating the variables.</p> |

There are basically two cases when Git changes may lead to replacements on SVN side:</p> <ol> <li><p>Force push.</p> <p>When one forcefully pushes non-fast-forward update, SubGit/SVN Mirror has nothing to do but delete current version of the branch and re-create it from some older revision, because this is exactly what non-fast-forward update does: continuing branch history from a commit other than the branch tip.</p></li> <li><p>Fast-forward merge from one branch into another.</p> <p>When one creates a new branch <code>foo</code> from <code>master</code>:</p> <pre><code>$ git checkout -b foo $ git commit -am 'fix foo' [foo ca3caf9] fix foo </code></pre> <p>then pushes that branch to SubGit mirror:</p> <pre><code>$ git push origin foo ... Sending commits to SVN repository: remote: ca3caf9 => r10 branches/foo </code></pre> <p>which gets <code>ca3caf9</code> mapped to <code>branches/foo@10</code>.</p> <p>Finally, one merges branch <code>foo</code> back to <code>master</code>:</p> <pre><code>$ git checkout master $ git merge foo Updating 0e39ad2..ca3caf9 Fast-forward </code></pre> <p>Noticed that <em>Updating ... Fast-forward</em> message? It means <code>git merge</code> found no new commits on <code>master</code>, hence there was no need to create a merge commit, i.e. <code>git merge</code> just moved the <code>master</code> pointer from older commit <code>0e39ad2</code> to a newer one <code>ca3caf9</code>.</p> <p>Now what happens when one pushes <code>master</code> to SubGit mirror:</p> <pre><code>$ git push origin master </code></pre> <p>SubGit finds out that <code>master</code> was updated from <code>0e39ad2</code> mapped to <code>trunk@9</code> to <code>ca3caf9</code> mapped to <code>branches/foo@10</code>. There's nothing SubGit can do but delete <code>trunk</code> and re-create it from <code>branches/foo@10</code> which obviously leads to replacement of <code>trunk</code>.</p></li> </ol> <p>And so we made sure that SubGit does not replace branches in these two scenarios unless SubGit administrator explicitly sets the following configuration option:</p> <pre><code>$ edit REPO/subgit/config ... [svn] allowBranchReplacement = true ... $ subgit install REPO </code></pre> <p>However, I'd recommend to keep <code>svn.allowBranchReplacement</code> set to <code>false</code> and follow these best practices to avoid the error message reported in the original question:</p> <ul> <li><p>Never force push anything; prefer to merge, revert of branch out changes rather than overwrite them.</p></li> <li><p>When merging one branch into another add <code>--no-ff</code> option: it forces <code>git merge</code> to create a merge commit when it would rather do a fast-forward update otherwise:</p> <pre><code>$ git merge --no-ff foo </code></pre></li> </ul> |
29,424,477 | 0 | How do I make a hotkey to activate a specific VMware Workstation VM? <p>I'm using the latest version of VMware Workstation (11.1.0) on Windows 7 x64 and I want to be able to do a keystroke of "Ctrl + 1" to go to VM #1, "Ctrl + 2" to go to VM #2, and "Ctrl + 3" to go to VM #3.</p> <p>Sounds simple right? It isn't.</p> <p>On Mac OS X, achieving this functionality is trivial with VMware Fusion in combination with Spaces / Mission Control - you can simply put each VM on a separate space and then define whatever space hotkeys you want. I'm migrating from OS X and want this same functionality.</p> <p>For reference, here are some potential solutions that I've tried and can verify that they don't work:</p> <p><strong>1) AutoHotkey</strong></p> <p>AutoHotkey can be used to make hotkeys like so:</p> <pre><code>^1::WinActivate, Win7(1) - VMware Workstation ^2::WinActivate, Win7(2) - VMware Workstation ^3::WinActivate, Win7(3) - VMware Workstation </code></pre> <p>These work to <strong>enter</strong> the VMs, but not to exit; Workstation will feed the "Ctrl + 1" to the VM and AutoHotkey does not take precedence, even if AutoHotkey is run as an administrator.</p> <p><strong>2) Suspend/Unsuspend with AutoHotkey</strong></p> <p>This promising post suggests that suspending and that unsuspending AutoHotkey while the VMware window is active will fix the problem:</p> <p><a href="http://superuser.com/questions/232762/autohotkey-script-to-exit-vmware-window">http://superuser.com/questions/232762/autohotkey-script-to-exit-vmware-window</a></p> <p>However, even after copying the exact code and making the necessary string modifications, I can't get it to work with Workstation.</p> <p><strong>3) Remote Desktop and/or VNC</strong></p> <p>One possible solution, if all 3 of the VMs in question were running Windows, would be to use Microsoft's Remote Desktop feature. However, one or more of the VMs that I intend to use will be running Linux.</p> <p>On Linux, it is possible to just use VNC. However, VNC has considerable drawbacks when compared to the native VMware Workstation console window: there is no sound, the resolution won't automatically scale, the performance will be bad, and so forth.</p> <p>Lastly, the VMs will be on 1) networks that won't be connected to the host via a bridged NIC (with the NIC disabled on the host) and 2) using a VPN without any split tunnel. So there will be no connectivity for either remote desktop or VNC in the first place.</p> <p><strong>3) A Windows Keyboard Hook</strong></p> <p>Liuk explains how to use a Windows hook to intercept keystrokes using C++: </p> <p><a href="http://polytimenerd.blogspot.com/2011/02/intercepting-keystrokes-in-any.html" rel="nofollow">http://polytimenerd.blogspot.com/2011/02/intercepting-keystrokes-in-any.html</a></p> <p>However, after testing with the demo program, it seems that this method does not intercept keystrokes sent to VMware Workstation.</p> <p><strong>4) FullScreenSwitch.directKey</strong></p> <p>It seems that in VMware Workstation used to have this kind of functionality built in, as documented in this SuperUser thread:</p> <p><a href="http://superuser.com/questions/71901/vmware-workstation-keyboard-shortcut">http://superuser.com/questions/71901/vmware-workstation-keyboard-shortcut</a></p> <p>However, VMware's documentations states that this is for VMware Workstation 5.0. I tried adding these strings to my VMX file and they had no effect, so the functionality must have been depreciated somewhere along the lines between Workstation 5 and 11.</p> <p><strong>5) PSExec</strong></p> <p>Wade Hatler mentions that he accomplishes this using PSExec to activate the appropriate AutoHotkey script on the host machine:</p> <p><a href="http://www.autohotkey.com/board/topic/64359-sending-keystrokes-to-vmware-player/" rel="nofollow">http://www.autohotkey.com/board/topic/64359-sending-keystrokes-to-vmware-player/</a></p> <p>This solution is questionable in that you have to keep the password of your host machine in plaintext in order to pass it to PSExec.</p> <p>Regardless, this solution will not work for the reasons also described in #2 above: the VMs in question will be on 1) networks that won't be connected to the host via a bridged NIC (with the NIC disabled on the host) and 2) using a VPN without any split tunnel. So there will not be guaranteed connectivity between the host and the guest.</p> <p><strong>6) Execute a "Host" keystroke between every "Ctrl + #" keystroke</strong></p> <p>This is problematic in that it doubles the amount of keystrokes involved and makes it impossible to "flip" through all of my VMs by holding down control and hitting 1 + 2 + 3 + 4 + 5, and so forth.</p> <p><strong>7) Use the "Host + Left/Right Arrow" hotkey and/or VMware-KVM.exe for cycling functionality</strong></p> <p>This is problematic in that when I have 10 or more VMs open at a time, rotating through all of them becomes incredibly cumbersome and inefficient.</p> |

For one, you shouldn't need that <code>height: 14px</code> on each image, you can state that with CSS.

36,819,972 | 0 | LC-3 Motor Program (Strange Outputs) <p>So the output to my LC-3 program is giving me very strange characters/symbols. The objective of this program is to ask a user to input a 0 or a 1. If the user inputs a 1, the motor moves 120 degrees clockwise and then 90 degrees counter clockwise. If the user inputs a 0, the motor moves 50 degrees counter clockwise. 360 degrees = 36 steps. What is a step? A step is 10 degrees. The output prints out each step. For example, the user inputs a 0 then the output should say:</p> <pre><code>The motor moved 10 degrees CCW The motor moved 10 degrees CCW The motor moved 10 degrees CCW The motor moved 10 degrees CCW The motor moved 10 degrees CCW </code></pre> <p>It's a pretty interesting task imo but I'm having trouble actually making it work.

34,618,413 | 0 | <p>I've found the cause of the problem. It's actually very simple but also pretty frustrating.</p> <p>When publishing the web app, you have the option to <code>Remove additional files at destination</code>. I have always left this checked because I don't like old files hanging around for no reason. </p> <p>You also have the option to <code>Exclude files from the App_Data folder</code> which I also always leave checked so that files from <code>App_Data</code> are not deleted based on the remove configuration above. I then usually configure things like NLog log files, ELMAH xml files etc to go into <code>App_Data</code> safe in the knowledge that anything in there won't be deleted.</p> <p>So the issue with Webjobs is that they're deployed into <code>App_Data</code>. So if the <code>Exclude files from App_Data folder</code> is checked then when the app is published, it's doing what it's told and ignoring <code>App_Data</code> and hence ignoring the changes to the Webjob. </p> <p>So the simple solution is to uncheck this option and the Webjob is deployed successfully. However the issue now is that all other files in <code>App_Data</code> will be deleted (log files etc). </p> <p>So you could uncheck the remove files config but that then potentially leaves other unwanted files lying around. Not ideal. </p> <p>The other option is to leave the remove config checked, click the Preview button within the Publish dialog prior to publishing, then manually unchecking every file you don't want deleted. However the publish process fails if any of the files you want to keep are within sub-folders within <code>App_Data</code> e.g. <code>App_Data/logs</code>.</p> <p>So the other option is to move all of the files within <code>App_Data</code> that you want to keep into the root of <code>App_Data</code>, then uncheck each of them within the Preview window prior to publishing. Not a huge deal when done once but becomes tedious when publishing lots of times.</p> <p>I realise I could move log files etc to Azure storage, SQL DBs etc but what if it's the case that other files are in <code>App_Data</code> which need to be kept? <code>App_Data</code> isn't solely intended for Webjobs but using Webjobs creates a bit of an awkward situation if you also use <code>App_Data</code> for other things. </p> <p>Be keen to know if I'm missing anything obvious here?</p> |

27,838,495 | 0 | Finding the difference between a time and the current time <p>So I'm writing an app that has similar functionality to an alarm clock. It asks for the user to input a time. But I've been stuck on how to figure this out for a while.</p> <p>The method needs to find the difference in minutes between the user selected time, and the current time. Assuming that the user will always put in a time that is AFTER the current time (otherwise it wouldn't make sense to use my app), the difference would just be (userTimeInMins - currTimeInMins), where both are calculated by ((hours * 60) + minutes).</p> <h2>BUT. Here's the problem:</h2> <p>Ex 1) If the current time is 10 PM, and the user enters in the time 2 AM. The above algorithm would say that the difference between the two times is (22 * 60 + 0) - (2 * 60 + 0), which is clearly incorrect because this would mean there is a difference of 20 hours between 10PM and 2 AM, when the difference is actually 4 hours. <br/> <br/> Ex 2) If the current time is 1PM, and the user enters in the time 2AM. The above algorithm would say that the difference between the two times is (13 * 60 + 0) - (2 * 60 + 0), which is again incorrect because this would mean there is a difference of 11 hours, when the difference is actually 13 hours.</p> <h2>What I have so far</h2> <p>I've realized that for example 1 and for example 2, the difference in minutes can be calculated with (((24 + userHours) * 60) + userMinutes) - currTimeInMins</p> <p>I'm struggling to come up with decision statements in the method to determine whether to use the first method or the second method to calculate the difference in minutes.</p> <h2>The Code</h2> <pre><code>// Listener for the time selection TimePickerDialog.OnTimeSetListener time = new TimePickerDialog.OnTimeSetListener() { @Override public void onTimeSet(TimePicker view, int hourOfDay, int minute) { String currAM_PM = ""; String userAM_PM = ""; // Get user AM/PM int hourToShow = 0; if (hourOfDay > 12){ hourToShow = hourOfDay - 12; userAM_PM = "PM" } else if (hourOfDay == 12){ hourToShow = hourOfDay; userAM_PM = "PM" } else{ hourToShow = hourOfDay; userAM_PM = "AM" } // Update the time field to show the selected time in 12-hr format EditText timeField = (EditText) findViewById(R.id.editTime); timeField.setText(hourToShow + ":" + minute + " " + userAM_PM); // Get current hour SimpleDateFormat sdf = new SimpleDateFormat("HH"); String cHour = sdf.format(new Date()); int currHour = Integer.parseInt(cHour); // Get current AM/PM if (currHour > 12){ currAM_PM = "PM" } else if (currHour == 12){ currAM_PM = "PM" } else{ currAM_PM = "AM" } // Calculate the time to use // If the selected hour is less than the current hour AND am_pm is "AM" // THIS IS THE WHERE I NEED HELP //-------------------------------------------------------------- if(currAM_PM == "PM" && userAM_PM == "AM" .... ??????) { //take 24, add the hour, use same minute. so that 3 am is 27:00. timeToUse = ((24 + hourOfDay) * 60) + minute; } else timeToUse = (hourOfDay * 60) + minute; } // timeToUse is then passed through an intent extra to the next activity // where the difference between it and the current time is calculated and used // for other purposes. }; </code></pre> <h2>Thanks for any help ahead of time.</h2> |

Runs great on my computer, when I publish it to my web account it no longer works with the service. I tried editing the clintconfig file to set the endpoint to the new location, that did not fix it. So I downloaded this simple SilverLight App with WCF example setup for deploying, and it also works on my personal machine, but not when I publish it to my domain.

21,696,873 | 0 | <p>The initial problem stems from the restriction that contracts cannot modify the object they belong to (otherwise, the program might behave differently in debug and release mode). The way the language enforces that restriction is by making the <code>this</code> pointer <code>const</code>.</p> <p>A <code>const this</code> means is that you can't modify the <code>this</code> object's fields, and as for calling methods - those methods themselves must be annotated as <code>const</code>, and the same restrictions apply to the code of those methods. This explains the first error: the contract, which was <code>const</code>, was trying to call a non-<code>const</code> (mutable) method. Since mutable methods are allowed to modify <code>this</code>, and contracts are forbidden to do so, the compiler forbids the call.</p> <p>Because of the transitive nature of D's constness, everything that's accessed through the <code>this</code> pointer becomes <code>const</code>. And, if any of the class fields are reference types, the target of their indirections becomes <code>const</code> too. This is how the type system will forbid modifying anything that can be reached through the <code>this</code> pointer.</p> <p>The implication of this is that if a <code>const</code> method is trying to return a class field (with indirections, such as a class type like <code>Node</code>), the returned type must also be <code>const</code>. This is the source of the second error message: the return expression attempted to convert the <code>const Node</code> value, obtained through the <code>const this</code>, to a mutable <code>Node</code>. Currently, the syntax <code>@property const Node sub()</code> indicates that the method itself is <code>const</code> (and has as <code>const this</code>), not the return type.</p> <p>Now, generally, in C++, an object with proper constness support will usually have multiple overloads for the methods which return a class field: <code>const</code>, and non-<code>const</code>. The <code>const</code> versions will return a <code>const</code> reference; the non-<code>const</code> will return a non-<code>const</code> reference. The two versions are needed to allow obtaining a mutable field reference when we have access to a mutable object, but still allow getting a <code>const</code> reference if we only have <code>const</code> access to the object. Most of the time, the code of the two methods will be identical - only the function signature will differ.</p> <p>This is where D's <code>inout</code> comes in. Specifying it on the method and some of its arguments or return value means that those arguments or return value will have the same constness as that of <code>this</code> (the object being referred to). This avoids code duplication for the simple cases where returning <code>const</code> and mutable values uses the same code.</p> <p>The syntax I used is <code>@property inout(Node) sub() inout</code>. I think it can be written in more than one way, but this syntax is unambiguous. Here, the parens in <code>inout(Node)</code> make it explicit that we apply the attribute on the return value, and not the function, and placing the method (<code>this</code>) <code>inout</code> attribute after the parameter list, like <code>const</code> in C++, unambigously specifies that it applies to the function itself.</p> |
