A Factory can be used to create an instance of a particular subclass of some general base class.
Each subclass registers itself with the Factory, supplying a function that will construct an instance of that subclass; the Factory can later choose a suitable subclass and return a newly-constructed pointer to an object of that type on the user's demand. This is used, for instance, to manage the set of GraphicsPipes available to the user.
This is a thin template wrapper around FactoryBase. All it does is ensure the types are correctly cast. All of its methods are inline, and it has no data members, so it is not necessary to export the class from the DLL.
Type * Factory< Type >::make_instance | ( | TypeHandle | handle, |
const FactoryParams & | params = FactoryParams() |
||
) | [inline] |
Attempts to create a new instance of some class of the indicated type, or some derivative if necessary.
If an instance of the exact type cannot be created, the specified preferred will specify which derived class will be preferred.

Type * Factory< Type >::make_instance | ( | const string & | type_name, |
const FactoryParams & | params = FactoryParams() |
||
) | [inline] |
Attempts to create a new instance of some class of the indicated type, or some derivative if necessary.
If an instance of the exact type cannot be created, the specified preferred will specify which derived class will be preferred.
This flavor of make_instance() accepts a string name that indicates the desired type. It must be the name of some already-registered type.

Type * Factory< Type >::make_instance_more_general | ( | TypeHandle | handle, |
const FactoryParams & | params = FactoryParams() |
||
) | [inline] |
Attempts to create an instance of the type requested, or some base type of the type requested.
Returns the new instance created, or NULL if the instance could not be created.
