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<Triple>

Returns:

true if it was successfully closed.
