How to decrease the number of possible cache misses when designing a C++ program? Does inlining functions help every time? or is it good only when the program is CPU-bounded (i.e. the program is computation oriented not I/O oriented)? ...
How do you do "inline functions" in C#? I don't think I understand the concept. Are they like anonymous methods? Like lambda functions? ...
Howdy all. I'd like to know if it's possible to determine what inline styling has been attributed to an HTML element. I do not need to retrieve the value, but rather just detect if it's been set inline or not. For instance, if the HTML were: <div id="foo" style="width: 100px; height: 100px; background: green;"></div> How can I dete...
I have highly optimized piece of C++ and making even small changes in places far from hot spots can hit performance as much as 20%. After deeper investigation it turned out to be (probably) slightly different registers used in hot spots. I can control inlineing with always_inline attribute, but can I control register allocation? ...
Say you override operator* for point3 and float and then for float and point3 you used the operator like this: point3 * float Can you know if the operator method is going to end up inlined? ...
Guys, I’m having difficulty referencing one main VB file from a new vb file. Here's the problem - the code file is ancient, and runs on ASP.NET 1.1. It runs without being compiled to a DLL, and changes regularly. for that reason, I'd rather not compile either New Person or Old Person to a DLL. A default page look something like this....
I used to use doxygen lot for C++, and really like the ability to document function and method arguments inline using ///< , or variations. Conversely I really dislike having to repeat arguments in the comments when not using the inline style (as most over code doc systems only support). So recently I've been setting up doxygen with my ...
Hi I'm trying to give a fadeout & delete to a DIV(id = "notification"), when a image is clicked. This is how I'm doing that: <a onclick="$("#notification").fadeOut(300,function() { $("#notification").remove(); });" class="notificationClose "><img src="close.png"/></a> This seems to not be working. What I need to do to fix this? Than...
Some people love using inline keyword in C, and put big functions in headers. When do you consider this to be ineffective? I consider it sometime even annoying, because it is unusual. My principle is that inline should be used for small functions accessed very frequently, or in order to have real type checking. Anyhow, my taste guide me...
Explain about linkages(external/internal) in c++? How does linkage differ for a function,constant,inline function,template function ,class and template class ...
I'm writing an XNA game where I do per-pixel collision checks. The loop which checks this does so by shifting an int and bitwise ORing and is generally difficult to read and understand. I would like to add private methods such as private bool IsTransparent(int pixelColorValue) to make the loop more readable, but I don't want the overhea...
I have a static event in a static method that I am temporarily attaching to, as I don't want it to hang around in memory, or get in a situation where I am firing two event handlers if I call it twice. I have little say in whether these should be static or not, and would prefer not to have the discussion / refactor responsibility. Initi...
C++ ISO standard says, that: "A function defined within a class definition is an inline function." Are there any compilers that IGNORE this rule? (please, do not mistake inline with inlineD - my question is if there is a compiler, that wont put there that inline suggestion that it should) ...
C++ ISO standard says: "A function defined within a class definition is an inline function." * Do you know about any compilers that IGNORE this rule? Do you know about any compilers that WILL NOT put that 'inline suggestion' there? (please do not repeat the theory about inlines, I am aware of that - I need a practical answer) ...
Example first: template <class HashingSolution> struct State : public HashingSolution { void Update(int idx, int val) { UpdateHash(idx, val); } int GetState(int idx) { return ...; } }; struct DummyHashingSolution { void UpdateHash(int idx, int val) {} void RecalcHash() {} }; struct MyHashingSolution { void Upd...
Up till a while a ago my code base was very close to #include hell. Every time I changed an even mildly important .h file practically all the files got recompiled. The main reason for such high header dependency was that I have many small functions that need to be inline and I was under the impression that for inline to work they need to...
Hello Does anybody know if it is the way to set control's child attributes properties by inline code? I mean something like that <asp:MenuItem Text="text" NavigateUrl='<%# GetItemURL("val") %>' ></asp:MenuItem> CodeBehind protected string GetItemURL(string tag) { if (string.IsNullOrEmpty(_pageUrl))...
Is one of these faster? inline int ProcessByValue(int i) { // process i somehow } inline int ProcessByReference(const int& i) { // process i somehow } I know that integral types should be passed by value. However, I am concerned that the compiler might inline ProcessByValue to contain a copy. Is there a rule for this? ...
Hi. There are some standard tools to do this, but I need a simple GUI to assist some users (on windows). They will get an open file dialog and pick the file to process. The file will be an XML file. The file will contain (within the first few lines) a text string that needs to be deleted or replaced with whitespace (doesn't matter which...
I got this question when I received a code review comment saying virtual functions need not be inline. I thought inline virtual functions could come in handy in scenarios where functions are called on objects directly. But the counter-argument came to my mind is -- why would one want to define virtual and then use objects to call metho...
