Class QueryCacheLookup<T>

java.lang.Object

com.neurosys.modules.etl.QueryCacheLookup<T>

All Implemented Interfaces:

Lookup, CacheLookups, org.apache.commons.collections.Transformer

Direct Known Subclasses:

EntityParamQueryLookup

Deprecated.

@see CacheLookup

public class QueryCacheLookup<T>
extends Object
implements Lookup, CacheLookups

Allow generic Query as a String and cache the result List (if {cache is defined)
The Query String should be acceptable to the PersistenceContext

If the Lookup accepts query params then ensure caching is disabled by cache not being set/defined or else one may get unexpected/dirty results.
