Constructor Detail

NodeIteratorImpl

public NodeIteratorImpl(java.util.Iterator iter,
                        java.lang.Object object)

Creates new NodeIteratorImpl

Method Detail

hasNext

public boolean hasNext()
                throws RDFException

Description copied from interface: NodeIterator

Determine if there any more values in the iteration.

Specified by:

hasNext in interface NodeIterator

Following copied from interface: com.hp.hpl.mesa.rdf.jena.model.NodeIterator

Returns:

true if and only if there are more values available from the iteration.

Throws:

RDFException - Generic RDF exception.

next

public RDFNode next()
             throws java.util.NoSuchElementException,
                    RDFException

Description copied from interface: NodeIterator

Return the next RDFNode of the iteration.

Specified by:

next in interface NodeIterator

Following copied from interface: com.hp.hpl.mesa.rdf.jena.model.NodeIterator

Returns:

The next RDFNode from the iteration.

Throws:

java.util.NoSuchElementException - if there are no more nodes to be returned.

RDFException - Generic RDF exception.

remove

public void remove()
            throws java.util.NoSuchElementException,
                   RDFException

Description copied from interface: NodeIterator

Unsupported Operation.

Specified by:

remove in interface NodeIterator

Following copied from interface: com.hp.hpl.mesa.rdf.jena.model.NodeIterator

Throws:

java.util.NoSuchElementException -

RDFException -

close

public void close()
           throws RDFException

Description copied from interface: NodeIterator

Terminate the iteration and free up resources.

Some implementations, e.g. on relational databases, hold resources while the iterator still exists. These will normally be freed when the iteration completes. However, if an application wishes to ensure they are freed without completing the iteration, this method should be called.

Specified by:

close in interface NodeIterator

Following copied from interface: com.hp.hpl.mesa.rdf.jena.model.NodeIterator

Throws:

RDFException - Generic RDF exception.
