test

public boolean test(org.apache.jena.graph.Triple t)

Specified by:

getMatchTriple

public org.apache.jena.graph.Triple getMatchTriple()

Description copied from interface: TripleConstraint

A possibly (less selective) representation of the constraint as a match triple suitable for pre-filtering using Graph.find(Triple) Must never return null. The most unselective triple pattern is Triple.createMatch(null, null, null).

Specified by:

getMatchTriple in interface TripleConstraint

Returns:

isMatchTripleExhaustive

public boolean isMatchTripleExhaustive()

Description copied from interface: TripleConstraint

True if TripleConstraint.getMatchTriple() matches the same set of triples as TripleConstraint.getExpr().

Specified by:

isMatchTripleExhaustive in interface TripleConstraint

getExpr

public org.apache.jena.sparql.expr.Expr getExpr()

Description copied from interface: TripleConstraint

An expression which only allows a subset of the variables ?s ?p and ?o

Specified by:

getExpr in interface TripleConstraint
