Description

Generic factory for wrapper objects.

The factory template can be instaniated to generate different kinds of factories. The generated factory takes objects of typeInternalType, and generates a wrapper object of typeWrapperType.

Parameters

InternalType

Base type for all objects that are stored inside the wrapper objects of typeWrapperType

WrapperType

Base type for all objects that are generated by the factory

IdentifierType

Type of the identifier that specifies which object creator to call

** ObjectCreator **

Type for callable entities that take an object of typeInternalType, and generate an object of typeWrapperType

FallbackPolicy

Template with a functiononUnknownType()that handles the case that the requested object type was not found
