Class CachingWrapperFilter

Implemented Interfaces:
Serializable
public class CachingWrapperFilter
extends Filter
Wraps another filter's result and caches it. The caching behavior is like QueryFilter. The purpose is to allow filters to simply filter, and then wrap with this class to add caching, keeping the two concerns decoupled yet composable.
