java.lang.Object

cz.cvut.kbss.ontodriver.rdf4j.loader.GraphDBStatementLoader

public class GraphDBStatementLoader
extends StatementLoader

Statement loader for GraphDB repositories.

It differs from the basic StatementLoader in the way inferred statements are loaded. This is because GraphDB does not store inferred statements in the same context as the statements they are inferred from (as RDF4J does), but instead has a special implicit context for them.
