ThreeFixedIterator

public ThreeFixedIterator(SubjectNode subjNode,
                          PredicateNode predNode,

Method Detail

close

public boolean close()

Description copied from interface: ClosableIterator

Closes the iterator by freeing any resources that it current holds.

This must be done as soon as possible. Once an iterator is closed none of the operations on a iterator will operate i.e. they will throw an exception.

Specified by:

close in interface ClosableIterator<Molecule>

Returns:

true if it was successfully closed.

hasNext

public boolean hasNext()

Specified by:

hasNext in interface Iterator<Molecule>

next

public Molecule next()
              throws NoSuchElementException

Specified by:

next in interface Iterator<Molecule>

Throws:

NoSuchElementException

remove

public void remove()

Specified by:

remove in interface Iterator<Molecule>
