Interface ExpressionResultCacheForDeclaredExprLastColl

All Known Implementing Classes:

ExpressionResultCacheForDeclaredExprLastCollImpl

public interface ExpressionResultCacheForDeclaredExprLastColl

On the level of expression declaration: a) for non-enum evaluation and for enum-evaluation a separate cache b) The cache is keyed by the prototype-node and verified by a events-per-stream (EventBean[]) that is maintained or rewritten. NOTE: ExpressionResultCacheEntry should not be held onto since the instance returned can be reused.
