Class StageGeneratorGraphFindRaw

java.lang.Object
org.apache.jena.sparql.engine.main.StageGeneratorGeneric
org.aksw.jena_sparql_api.io.binseach.StageGeneratorGraphFindRaw
All Implemented Interfaces:
org.apache.jena.sparql.engine.main.StageGenerator
public class StageGeneratorGraphFindRaw extends org.apache.jena.sparql.engine.main.StageGeneratorGeneric
Variant of stage generator for aborting find() calls on graph implementations that may require a long time until the next binding can be produced. The filtering of candidates is moved to the QueryIter level.
