Interface MethodLookup

Functional Interface:

This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.

@FunctionalInterface
public interface MethodLookup

Strategy interface providing predicates to resolve a method called on a composite to its implementation method.

Predicates are ordered by filtering priority and applied individually. If a predicate does not yield any positive match, the next predicate is applied.
