Class AdviceContextImpl

java.lang.Object
  org.eclipse.xtend.backend.aop.internal.AdviceContextImpl

All Implemented Interfaces:

AdviceContext

public final class AdviceContextImpl
extends java.lang.Object
implements AdviceContext

This class represents all currently registered advice. It is designed to efficiently handle dynamically registered advice, e.g. for the scope of an invocation.
In order to allow aggressive caching, it is immutable and creates a copy when additional advice is registered. This design decision assumes that registering new advice is very infrequent compared to the invocation of functions.
