Class QuadSignature

java.lang.Object

sparql.QuadSignature

All Implemented Interfaces:

IPatternSignature

public class QuadSignature
extends Object
implements IPatternSignature

A Quad Pattern signature would be the set of QuadSignatures. A quad signature associates either a variable symbol or a set of (positive and negated) values with each term in the quad. The idea behind this is to quickly identify compatible patterns. Given a pattern such as { ?s ?p ?o . Filter(?s = Person, ?p != subClass && ?p != type). } The signature would be (+[person], -[subClassOf, type], var1)
