Class BigdataTripleSource

java.lang.Object
  com.bigdata.rdf.sail.BigdataTripleSource

All Implemented Interfaces:

org.openrdf.query.algebra.evaluation.TripleSource

public class BigdataTripleSource
extends Object
implements org.openrdf.query.algebra.evaluation.TripleSource

TripleSource API - used by high-level query.

Note: We need to use a class for this since the behavior is parameterized based on whether or not inferred statements are to be included in the query results.
