Class SubsumedCondition

java.lang.Object

org.hypergraphdb.query.SubsumedCondition

All Implemented Interfaces:

HGAtomPredicate, HGQueryCondition

public class SubsumedCondition
extends Object
implements HGQueryCondition, HGAtomPredicate

The SubsumedCondition examines a given atom and is satisfied if that atom is subsumed by the atom specified in the condition. You can also provide a value instead of a HyperGraph handle by using the SubsumedCondition(Object) constructor.
