Detailed Description

Postorder Iterator on a trie.

_cur points to the current object, _root contains the search key for root of the subtree we want to scan. The iterator skips over empty nodes, and visits the subtree in depth-first, left-to-right order. The keys returned by this iterator are not sorted by prefix length.

Constructors

 RefTriePostOrderIterator (const RefTrie* trie, Node *n)

RefTriePostOrderIterator

constructor for exact searches: both the current node and the search key are taken from n, so the iterator will only loop once.

 RefTriePostOrderIterator (const RefTrie* trie, Node *n, const Key &k)

RefTriePostOrderIterator

construct for subtree scanning: the root key is set explicitly, and the current node is set according to the search order.

RefTriePostOrderIterator  operator ++ (int)

operator ++

Postfix increment

Updates position of iterator in tree.

Returns: position of iterator before increment.

RefTriePostOrderIterator&  operator ++ ()

Prefix increment

Updates position of iterator in tree.

Returns: position of iterator after increment.
