Factories::CFactoryBase Class Reference

class Factories::CFactoryBase : public CBase

Factory Base class provides basic object managment functionlity and the ability for a factory to be load from another Dynamic Linked Library via the ECOM framework.

It also provides asynchronous destruction for it's managed objects (if required) but also copes with synchronous destruction, should a managed object get deleted by another entity.
