Class SimpleInvocationCacheMixin

java.lang.Object

org.apache.polygene.library.invocationcache.SimpleInvocationCacheMixin

All Implemented Interfaces:

InvocationCache

public class SimpleInvocationCacheMixin
extends Object
implements InvocationCache

Simple implementation of InvocationCache.

This InvocationCache should typically not be used at all, and only serves as an example. The @{code cachedValues} member is never emptied, so it constitutes a memory leak if the method arguments keep changing.

IMPORTANT: Only use this is you know that only a small set of arguments are used into your method(s).
