Constructor Detail

NsIteratorImpl

public NsIteratorImpl(java.util.Iterator iter,
                      java.lang.Object o)

Creates new NsIteratorImpl

Method Detail

hasNext

public boolean hasNext()
                throws RDFException

Description copied from interface: NsIterator

Determine if there any more values in the iteration.

Specified by:

hasNext in interface NsIterator

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

Returns:

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

Throws:

RDFException - Generic RDF exception.

next

public java.lang.String next()
                      throws java.util.NoSuchElementException,
                             RDFException

Description copied from interface: NsIterator

Return the next namespace name of the iteration.

Specified by:

next in interface NsIterator

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

Returns:

The next name space URI from the iteration.

Throws:

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

RDFException - Generic RDF exception.

remove

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

Description copied from interface: NsIterator

Unsupported Operation.

Specified by:

remove in interface NsIterator

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

Throws:

java.util.NoSuchElementException -

RDFException -

close

public void close()
           throws RDFException

Description copied from interface: NsIterator

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 NsIterator

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

Throws:

RDFException - Generic RDF exception.
