Class ShadowCache

java.lang.Object

org.eclipse.ocl.pivot.internal.evaluation.ShadowCache

public class ShadowCache
extends java.lang.Object

An ShadowCache caches the results of each distinct operation implementation and source and argument value for re-use if the same implementation is re-attempted. The cache is normally accessed as a consequence of AbstractOperation.evaluate redirecting to the cache. A call-back to AbstractOperation.basicEvaluate occurs when evaluation is actually necessary. The cache is bypassed for derived implementations that override AbstractOperation.evaluate.
