All known Subclasses: com.hp.hpl.jena.rdf.model.impl.StatementImpl,
| Statement | | public interface Statement extends FrontsTriple(Code) | | 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.

statement. This is not what is wanted in most cases, so getProperty
on a statement is defined to call getProperty on its object. If
a property of the statement itself is required, getStatementProperty
should be used.

The model associated with this statement is searched for a statement with
this statement as subject and the specified property as predicate. If
such a statement is found it is return. If more than one exists in the
model, then it is undefined which is returned. If no such statement
exists, an exception is thrown.

The subject of the statement. |
