Factory< T > Class Template Reference

Detailed Description

template<class T>
class asl::Factory< T >

A Factory allows creating objects given a class name as a String.

They are used through pointers to their base class and through virtual functions. A Factory is created for a given base class, and subclasses must be registered with ASL_FACTORY_REGISTER() before use.

class Dog : public Animal {...};
 
ASL_FACTORY_REGISTER( Animal, Dog )
...
Animal* animal = Factory<Animal>::create("Dog");

#include <Factory.h>

Inherits Singleton< Factory< T > >.
