com.hp.hpl.jena.rdf.model.Statement
An RDF Statement.
A Statement is not a Resource, but can produce a ReifiedStatement that represents it and from which the Statement can be recovered.

A statement instance tracks which model created it, if any. All the Resource components of a Statement are in the same model as the Statement, if it has one, and are in no model if the Statement isn't.

This interface provides methods supporting typed literals. This means that methods are provided which will translate a built in type, or an object to an RDF Literal. This translation is done by invoking the toString() method of the object, or its built in equivalent. The reverse translation is also supported. This is built in for built in types. Factory objects, provided by the application, are used for application objects.
