Class ExistsSubQueryPredicate

java.lang.Object

org.kuali.rice.core.api.mo.AbstractDataTransferObject

org.kuali.rice.core.api.criteria.ExistsSubQueryPredicate

All Implemented Interfaces:

Serializable, Predicate, SubQueryPredicate, ModelObjectBasic, ModelObjectComplete

public final class ExistsSubQueryPredicate
extends AbstractDataTransferObject
implements SubQueryPredicate

An immutable predicate which represents an "WHERE EXISTS" statement. This implementation assumes that there is a single field which can be related between the inner and outer queries. An equality between those fields is automatically added to the predicates of the inner query.

Since:

Rice 2.4.2
