Constructor Detail

StmtIteratorImpl

public StmtIteratorImpl(java.util.Iterator iterator,
                        java.lang.Object object)

Creates new StmtIteratorImpl

Method Detail

hasNext

public boolean hasNext()
                throws RDFException

Description copied from interface: StmtIterator

Determine if there any more Statements in the iteration.

Specified by:

hasNext in interface StmtIterator

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

Returns:

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

Throws:

RDFException - Generic RDF exception.

next

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

Description copied from interface: StmtIterator

Return the next Statement of the iteration.

Specified by:

next in interface StmtIterator

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

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: StmtIterator

Remove the most recently returned Statement from its associated model.

Specified by:

remove in interface StmtIterator

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

Throws:

java.util.NoSuchElementException - thrown if no Statement has been returned.

RDFException - Generic RDF exception.

close

public void close()
           throws RDFException

Description copied from interface: StmtIterator

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 StmtIterator

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

Throws:

RDFException - Generic RDF exception.
