Constructor Detail

ResIteratorImpl

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

Creates new ResIterator

Method Detail

hasNext

public boolean hasNext()
                throws RDFException

Description copied from interface: ResIterator

Determine if there any more Resources in the iteration.

Specified by:

hasNext in interface ResIterator

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

Returns:

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

Throws:

RDFException - Generic RDF exception.

next

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

Description copied from interface: ResIterator

Return the next Resource of the iteration.

Specified by:

next in interface ResIterator

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

Returns:

The next Resource 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: ResIterator

Unsupported Operation.

Specified by:

remove in interface ResIterator

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

Throws:

java.util.NoSuchElementException -

RDFException -

close

public void close()
           throws RDFException

Description copied from interface: ResIterator

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 ResIterator

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

Throws:

RDFException - Generic RDF exception.
