Description

Generic factory for objects allowing lambdas with variable number of arguments as creator functions.

The factory template can be instaniated to generate different kinds of factories. The generated factory generates objects of typeObjectType.

Parameters

IdentifierType

Type of the identifier that specifies which object creator to call

FallbackPolicy

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