Parameters:

art - the ART

reverse - false: ascending order,true: the descending order

containers - the containers

from - starting upper/lower bound

Method Detail

hasNext

public boolean hasNext()

Specified by:

hasNext in interface java.util.Iterator<LeafNode>

next

public LeafNode next()

Specified by:

next in interface java.util.Iterator<LeafNode>

remove

public void remove()

Specified by:

remove in interface java.util.Iterator<LeafNode>

seek

public void seek(long boundval)

Move this iterator to the leaf that contains `boundval`. If no leaf contains `boundval`, then move to the next largest (on forward iterators or next smallest (on backwards iterators).

peekNext

public LeafNode peekNext()

Return the next leaf without advancing the iterator.

Returns:

the next leaf
