iterator

public NodeIterator iterator()

Description copied from interface: Container

Return an iterator over the values.

Note the iterator 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.

Specified by:

iterator in interface Container

Returns:

Return an iterator over the values.

return the number values in the container.

Specified by:

size in interface Container

Returns:

the number of values int the container.

remove

public Container remove(Statement s)

Description copied from interface: Container

Remove a value from the container.

The 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.

Specified by:

remove in interface Container

Parameters:

s - The statement to be removed from the model.

Returns:

this container to enable cascading calls.

remove

public Container remove(int index,
 RDFNode object)

listContainerMembers

public NodeIterator listContainerMembers()

Answer an iterator over the members of this container.

Returns:

containerIndexOf

public int containerIndexOf(RDFNode n)

containerContains

public boolean containerContains(RDFNode n)
