Autogenerate value objects
Given an interface or interfaces, what is the best way to generate an class implementation? interface Vehicle { Engine getEngine(); } @Generated class Car implements Vehicle { private final Engine engine; public Car(Engine engine) { this.engine = engine; } public Engine getEngine() { return...
Extracting Property Names For Reflection, with Intellisense and Compile-Time Checking
Ok. So I have some code that maps certain controls on a winForm to certain properties in an object, in order to do certain things to the controls when certain things happen to the data. All well and good, works fine. Not the problem. The issue is, to add items to the mapping, I call a function that looks like: this.AddMapping(this.m...
Runtime vs Compile time
Can anyone please give me a good understanding of whats the difference between run-time and compile-time? ...
Checking for the existence a reference/type at compile time in .NET
I've recently found the need to check at compile-time whether either: a) a certain assembly reference exists and can be successfully resolved, or b) a certain class (whose fully qualified name is known) is defined. These two situations are equivalent for my purposes, so being able to check for one of them would be good enough. Is there a...
Unable to understand a statement about compilers' optimization
I am interested in optimization at runtime by a VM and at compile-time. I have had the idea that optimizations are most efficient and easiest at compile-time. However, my thought seems to be false in certain circumstances. This is evident in Steve Yeggie's statement quoted by Daniel [O]ptimization is often easier when performed at r...
C++ Get name of type in template
I'm writing some template classes for parseing some text data files, and as such it is likly the great majority of parse errors will be due to errors in the data file, which are for the most part not written by programmers, and so need a nice message about why the app failed to load e.g. something like: Error parsing example.txt. Val...
Dynamically add files to visual studio deployment project.
I've been desperately looking for the answer to this and I feel I'm missing something obvious. I need to copy a folder full of data files into the TARGETDIR of my deployment project at compile time. I can see how I would add individual files (ie. right click in File System and go to Add->File) but I have a folder full of data files whi...
Is the C preprocessor able to process strings char by char?
I'd like to obscure strings at compile time. I know it can be done in other preprocessors but I haven't found a way to do this with the C preprocessor. ...
How to give dynamically created buttons actions for each one - part 2
Hi again fellow Flashers :) My first question poised here at StackOverFlow dealt with this issue, I had an array which created a few different buttons. However I didn't know how to assign actions to them: How to give dynamically created buttons actions for each one - part 1 Thanks to Joel Hooks, I was able to get my code working. Howev...
Edit VWD Default MVC project template configuration
I'd love to add <MvcBuildViews>true</MvcBuildViews> to the default MVC Project config. It's required if you wanna to find Errors in views at compile errors http://devermind.com/linq/aspnet-mvc-tip-turn-on-compile-time-view-checking/ ...
Infinite loop at compile time?
Is it possible to enter an infinite loop at compile time? My program seems to enter an infinite loop when I attempt to compile it. I have a class with a class constructor that calls the method gameRun(). gameRun() calls itself at the end of its execution, but should have the appropriate checks to be able to break from it during run time...
C# Compile-Time Concatenation For String Constants
Does C# do any compile-time optimization for constant string concatenation? If so, how must my code by written to take advantage of this? Example: How do these compare at run time? Console.WriteLine("ABC" + "DEF"); const string s1 = "ABC"; Console.WriteLine(s1 + "DEF"); const string s1 = "ABC"; const string s2 = s1 + "DEF"; Console....
C++ What is compile-time polymorphism and why does it only apply to functions?
The question is pretty much fully embedded in the title. ...
Min and Max values for integer variable at compile time in C++
Is there a simple, clean way of determining at compile time the max and min values for a variable of some (otherwise unknown at the moment) integer variable or type? Using templates? For example: // Somewhere in a large project is: typedef unsigned long XType; typedef char YType; // ... // Somewhere else XType a; YType b; LON...
Compile date and time
Is there a Java equivalent to the C & C++ compile-time constants __DATE__ and __TIME__. I need to print compile time and version info of the program being compiled. Thanks kodev19 ...
Using std::map<K,V> where V has no usable default constructor
I have a symbol table implemented as a std::map. For the value, there is no way to legitimately construct an instance of the value type via a default constructor. However if I don't provide a default constructor, I get a compiler error and if I make the constructor assert, my program compile just fine but crashes inside of map<K,V>::oper...
Do math functions of constant expressions get pre-calculated at compile time?
I tend to use math functions of constant expressions for convinience and coherence (i.e log(x)/log(2) instead of log(x)/0.3...). Since these functions aren't actually a part of the language itself, neither are they defined in math.h (only declared), will the constant ones get precalculated at compile time, or will they be wastefully calc...
How functions are resolved by compiler?
How it is determined whether the below call is bound at compile time or at runtime? object.member_fn;//object is either base class or derived class object p->member_fn;//p is either base class or derived class pointer EDITED: #include <iostream> using namespace std; class Base { public: Base(){ cout<<"Constructor: Ba...
Python: Do (explicit) string parameters hurt performance?
Suppose some function that always gets some parameter s that it does not use. def someFunc(s): # do something _not_ using s, for example a=1 now consider this call someFunc("the unused string") which gives a string as a parameter that is not built during runtime but compiled straight into the binary (hope thats right). The que...
