I have seen looking for a way to get the list of ProjectItems (files) for a known class, which generated from several partial classes. I use CodeModel to search for a class and accessing the ProjectItem to do stuff, which works fine for normal classes. But when it comes to partial classes, the ProjectItem property give one file but dont ...
I recently tried to understand a C++ program that was written by somebody who I assume had a background in functional programming: For example, he had declared a closure class which he extensively used and which does somewhat resemble what is known as a closure in functional programming. Another class was called a guard, but I haven't qu...

I've attempted to write a PHP class that gets the uptime of my Linux machine. It will get the uptime correctly, but I have an if statement that determines whether or not the load average is "high" or not and set a warning code, and it doesn't seem to be working (it stays at 0). I've included all of the code here from the class (50 or so...

Heres what I'm trying to do: A have a "Checkers" class and a "Board" class.

I have a bunch of C++ classes. I want each class to have something like: static int unique_id; All instances of a same class should have the same unique_id; different classes should have different unique_id's. The simplest way to do this appears to be threading a singleton through the classes. However, I don't know what's called w...

So, this question has been asked before, but I wanted a question with some of those key words in the title. The issue is simple: How can I have a templated class, such that for each instance of the template - but not each instance of the class - there is a unique, numerical identifier? That is, a way to differentiate: foo<int> f1; foo...
Hey Guys Quick question for you. I want to be able to create an instance of an object. The object type is based of a string. In php you can just replace the class name with a string, but I doubt it is that easy in Objective c. NSString * className; id theObject; className = @"TestObject"; theObject = [[className alloc] init]; here...
