+--com.hp.hpl.mesa.rdf.jena.common.EnhContainer
A base class for supporting enhanced containers. An enhanced resource is a resource with extended functionality, provided either by the application or by the implementation. This class is a base class with container functionality which can be extended by the application.
Enhanced resources are implemented using encapsulation. An enhanced resource contains an embedded resource which provides the basic functionality of the resource. The application code provides any extended behaviour. This method was chosen, rather than subclassing, so as not to constrain the applications need to create its own class hierarchy.
This class is intended to be subclassed by the application to provide the specific enhanced behaviour. It provides Container funcationality and some basic housekeeping functions to support the encapsulation.

RDFException - Generic RDF exception
public NodeIterator iterator()
throws RDFException
ContainerNote the interator returned is not a standard java.util.iterator.
It has a close method which SHOULD be called if the
application has not completed the iteration, but no longer requires
the iterator. This will enable the freeing of resources in, for
example, implementations which store their models in a database.
iterator in interface ContainerRDFException - Generic RDF exception.
public int size()
throws RDFException
Container
size in interface ContainerRDFException - Generic RDF exception
public Container remove(Statement s)
throws RDFException
ContainerThe predicate of the statement s identifies the
ordinal of the value to be removed. Once removed, the values in the
container with a higher ordinal value are renumbered. The renumbering
algorithm depends on the type of container.
remove in interface Containers - The statement to be removed from the model.
RDFException - Generic RDF Exception
public Container remove(int index,
RDFNode object)
throws RDFException
com.hp.hpl.mesa.rdf.jena.common.ContainerI
remove in interface com.hp.hpl.mesa.rdf.jena.common.ContainerIindex - The index at which the value should be removed.object - The object at that index to be removed
