public abstract class AbstractInvocationDelegate
extends Object

The JBoss Cache hand-wired interceptor stack. A "minimal" AOP framework which uses delegation through an interceptor chain rather than any bytecode manipulation.

This class provides some generic behaviour such as the construction of an InvocationContext which is passed up the interceptor chain.

2.1.0
