Class FullClosure

com.bigdata.rdf.rules.FullClosure

public class FullClosure
extends BaseClosure

A program that uses the fix point of the configured rules to compute the forward closure of the database. Since there is no inherent order among the rules in a fix point program, this program can be easily extended by adding additional rules.
