Class QueryTriple

java.lang.Object
  com.hp.hpl.jena.graph.query.QueryTriple

public class QueryTriple
extends java.lang.Object

A QueryTriple is a composite of three QueryNodes derived from a single source triple. QueryTriple knows how to classify a triple into a QueryTriple based on the classification of that triple's elements. A QueryTriple can create a specific Matcher which will do the minimal amount of work to match triples that have been generated by find on the finder of that QueryTriple.
