Detailed Description

template<class T>
class Factory< T >

Generalized static factory that can deliver instances of T, when no variable is needed in the creation.

Usage. Each implementation of the base class T must add themselves to the factory when application starts up, e.g. in an initClass() function:

class A
{
public:
    virtual int         myFunc()        = 0;
};

class B : public A
{
public:
    static A*           createFunc() { return new B; }
    static void         initClass()
                        { thefactory.addCreator(createFunc,"MyKeyword",
                                                "My Name"); }
                            
    int                 myFunc();
};

Two macros are available to make a static accessfuncion for the factory:

mDefineFactory( ClassName, FunctionName );

that will create a static function that returns an instance to Factory<ClassName>. If the function is a static member of a class, it has to be defined with the mDefineFactoryInClass macro.

The static function must be implemented in a src-file with the macro

mImplFactory( ClassName, FunctionName );
