Direct Known Subclasses:

public abstract class Invoker
extends java.lang.Object

An invoker represents the result of a method lookup operation in the type hierarchy.

It encapsulates a reference to a resolved method implementation in a reloadable or non-reloadable type and provides an 'invoke' method suitable for invoking that method implementation, and a 'createJavaMethod' to create a Java Method instance that can be used to represent the method in the Java reflection API.
