traverse

Description:

public void traverse (string key, TraverseType order, TraverseFlags flags, int max_depth, TrieTraverseFunc func)

Traverses all nodes of this according to the parameters.

For each node matching the traversal parameters, func will be executed.

Only g_pre_order and g_post_order are supported for order.

If max_depth is less than zero, the entire tree will be traversed. If max_depth is 1, then only the root will be traversed.

this	A Trie.
key	The key to start traversal from.
order	The order to traverse.
flags	The flags for which nodes to callback.
max_depth	the maximum depth to process.
func	The func to execute for each matching node.
user_data	User data for `func`.
