Public Member Functions
	traverser (action &_a, const std::string &_visit_order="pnc", TraverseStrategy _strategy=TS_DEPTH_FIRST, bool _stop_if_not_implemented=false, bool _ignore_activation_state=false)
	construct from reference on action and traversal order string

traverser &	set_visit_order (const std::string &_visit_order)
	set a different visiting order of node, children and parent

traverser &	set_strategy (TraverseStrategy _strategy)
	set a different traverse strategy

bool	traverse (base_ptr start, traverse_callback_handler *tch=0)
	traverse a tree starting at given node according to set strategy, order and dest and previously coming from src and return whether traversal yielded success
