Detailed Description

template<typename BaseClass, typename IdentifierType>
class claw::pattern::factory< BaseClass, IdentifierType >

The design pattern of the factory allow to dynamically instanciate classes of various types given an identifier of this type.

Template parameters:

• BaseClass A base class for all classes instanciated by this factory.
• IdentifierType The type of the identifiers of the classes instanciated by this factory.

Type requirements:

• IdentifierType must be "less than" comparable.
