 com.hp.hpl.jena.assembler.Mode
| Mode | | public class Mode (Code) | | A Mode object controls whether persistent objects can be created or reused
by an assembler. Their methods are expected to be called when an
assembler is about to create a new object (because no object with the given
name exists) or reuse an existing one (because one does).
The default behaviour of the methods is dictated by booleans bound into
the mode object. Subclasses of mode may exploit the ability to inspect the
name of the object or its other RDF properties.
