Interface MethodResolver

All Known Implementing Classes:

DataBindingMethodResolver, ReflectiveMethodResolver

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 MethodResolver

A method resolver attempts to locate a method and returns a MethodExecutor that can be used to invoke that method.

The MethodExecutor will be cached, but if it becomes stale the resolvers will be called again.
