Class TryBeforeMaterializationConstraint

java.lang.Object

com.bigdata.bop.CoreBaseBOp

com.bigdata.bop.BOpBase

com.bigdata.rdf.internal.constraints.TryBeforeMaterializationConstraint

All Implemented Interfaces:

BOp, IConstraint, IPropertySet, Serializable, Cloneable

public class TryBeforeMaterializationConstraint
extends BOpBase
implements IConstraint

This is useful when a solution can be filtered out before it goes through the materialization pipeline. Note that if a solution passes, it will still enter the materialization pipeline. It is up to the first step in the pipeline to ensure that the solution gets routed around the materialization steps. See IsMaterializedBOp.
