Description

Generic object cache for objects allowing lambdas with variable number of arguments as cache functions.

The cache template can be instaniated to generate different kinds of caches. The generated cache generates and caches objects of typeObjectType. It hashes the parameters used to create an object and stores it in a map. If an object with the same hash already exists, it is returned instead of creating a new one.

Parameters

ObjectType

Base type for all objects that are generated by the factory

IdentifierType

Type of the identifier that specifies which object cache to call

FallbackPolicy

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