public class JPQLQuery
extends org.datanucleus.store.query.AbstractJPQLQuery

JPQL query for LDAP datastores. Performs a simple LDAP search for all objects of the requisite "distinguished name" to limit it to the candidate class. Then utilises the generic JPQLEvaluator to do in-memory imposition of the JPQL filter, ordering, result etc.
