Allow to specify how interfaces/abstract classes are resolved about fixture-monkey HOT 4 CLOSED

@esfomeado
The issue I understand is that you need a new option to determine the implementation of the interface dynamically.
Is it right?

In order to define an interface, we need to know which implementations are actually available.
I think there are two ways.

1. Specify the package in which the implementation exists
2. Specify the implementations just like interfaceImplements

Any other ideas?

Yes, correct.

How would option 1 work if for instance there are multiple classes on that package that are not implementations of the interface? Will it handle sub packages as well?

My initial plan was to use reflection to get all the available implementations for the interface.

@esfomeado
How about making a custom ObjectPropertyGenerator or using existing ObjectPropertyGenerator?

If you use reflection to get all the available implementations and then make your own InterfaceObjectPropertyGenerator.

You could use pushAssignableTypeObjectPropertyGenerator option.

pushObjectPropertyGenerator(
    new MatherOperator<>(
        p -> Modifier.isAbstract(Types.getActualType(p.getType()).getModifiers()), 
        new CustomObjectPropertyGenerator()
    )
);

In this case, You could use third-party library. https://github.com/ronmamo/reflections/

@seongahjo Thanks. That's literally what I wanted.

Works like a charm
