canFactoryGenericFactory

Checks if a structure has factory method for GenericFactory.

This static interface is used by annotation system to identify annotations that mark an object as instantiable by container. The @component annotation is such a structure that implements this static interface and therefore it is possible to use it to mark components instantiable. A "@component" annotation must have a factory method that returns a GenericFactory instance that further will be used to configure an instantiable object. In such a way it is possbile to define other custom annotations that return GenericFactory implementations that add/or behave differrently comparing to default implementation of GenericFactory.

) if (
isAggregateType!T
) {
alias factory = getMember!(T, "factory");
alias checker = templateOr!(chain!(partialPrefixed!(isDerived, ReturnType!(factory!Z)), chain!(GenericFactory, Wrapper)), chain!(partialPrefixed!(isDerived, ReturnType!(factory!Z)), GenericFactory));
