Method Summary

ITupleIterator	entryIterator() Traversal of index values in key order.
Iterator<AbstractNode>	postOrderNodeIterator() Post-order traveral of nodes and leaves in the tree.

Method Detail

entryIterator

ITupleIterator entryIterator()

Traversal of index values in key order.

postOrderNodeIterator

Iterator<AbstractNode> postOrderNodeIterator()

Post-order traveral of nodes and leaves in the tree. For any given node, its children are always visited before the node itself (hence the node occurs in the post-order position in the traveral). The iterator is NOT safe for concurrent modification.

Returns:

Iterator visiting IAbstractNodes.
