Class RdbmsValueFactory

java.lang.Object

org.openrdf.model.impl.ValueFactoryBase

org.openrdf.sail.rdbms.RdbmsValueFactory

All Implemented Interfaces:

ValueFactory

public class RdbmsValueFactory
extends ValueFactoryBase

Provides basic value creation both for traditional values as well as values with an internal id. RdbmsValues behaviour similar to the default Value implementation with the addition that they also include an internal id and a version associated with that id. The internal ids should not be accessed directly, but rather either through this class or the corresponding manager class.
