所有已知实现类:: ReflectiveMethodExecutor

public interface MethodExecutor

A MethodExecutor is built by a MethodResolver and can be cached by the infrastructure to repeat an operation quickly without going back to the resolvers.

For example, the particular method to execute on an object may be discovered by a MethodResolver which then builds a MethodExecutor that executes that method, and the resolved MethodExecutor can be reused without needing to go back to the resolvers to discover the method again.

If a MethodExecutor becomes stale, it should throw an AccessException which signals to the infrastructure to go back to the resolvers to ask for a new one.
