What I'd like to do is check if the classes that are included in the list extend a particular class. I thought about parsing the file, looking for what is afte...

It looks like that: #ifndef SOME_CLASS_H #define SOME_CLASS_H #include <string> class mySomeClass { public: bool a_func(string & my...

Hello. I'm coming from AS3 to Obj-C, and classes are confusing me. I want to create a ball class as a test, with colour, radius etc. Looking through other people's code I've discovered they use structs to implement them, and this seems like a much nicer method. I've searched but am unable to find a really clear explanation of what st...

I have an helper class with some static functions. all the functions in the class requires a 'heavy' initialization function to run once ( like it was a constructor.. ). is there a good practice ? the only thing i thought of is calling 'init' function , and breaking it's flow if it already run once (using static $initialized var). pro...

I have feeling, that if one defines a method def test puts 'Hi' end then there is a class to which this method belongs to (i.e. Unknown#test). So one probably has a possibility to list all methods defined "outside" of other classes. Or there is another way to do such listing? ...

I have a standalone class I wrote in PHP for some very basic LDAP/AD functions. and I would like to use this class in a project I am working on in cakephp. It looks like in cakephp 1.2 I could just add the class as a vendor, however it looks like cakephp 1.3 removed support for vendors. So how would I go about calling a few function fro...

Here's an example of my problem : class bar() : spam = foo() def test(self) : print self.spam.eggs pass class foo() : eggs = 50 The issue (I assume) is that I'm trying to create an instance of a class before the class is defined. The obvious solution is to re-order my classes, but I like to keep my classes...
iPhone/Mac "play a sound class": link text I find an awful lot of great objective-c classes and code samples here... and elsewhere.

What if I need to play 2-3 different...
