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<Triple>
Returns:
true if it was successfully closed.

hasNext

public boolean hasNext()
Specified by:
hasNext in interface Iterator<Triple>

next

public Triple next()
Specified by:
next in interface Iterator<Triple>

remove

public void remove()
Specified by:
remove in interface Iterator<Triple>
