Class RepositoryDataSource

java.lang.Object

org.streampipes.empire.core.empire.ds.impl.AbstractDataSource

org.streampipes.empire.rdf4j.RepositoryDataSource

All Implemented Interfaces:

DataSource, MutableDataSource, SupportsNamedGraphs, SupportsTransactions, TripleSource

public final class RepositoryDataSource
extends AbstractDataSource
implements MutableDataSource, TripleSource, SupportsNamedGraphs, SupportsTransactions

Implementation of the DataSource interface(s) backed by a Sesame 2 repository. This can be used as a base class for any back-end which supports the Sesame 2 SAIL api, such as BigData, OWLIM, Neo4j, and others.
