Public Member Functions
virtual bool	on_enter_node (base_ptr b)
	called before a node b is processed, return, whether to skip this node. If the node is skipped, the on_leave_node callback is still called
virtual bool	on_leave_node (base_ptr b)
	called when a node b is left, return whether to terminate traversal
virtual bool	on_enter_children (group_ptr g)
	called before the children of a group node g are processed, return whether these should be skipped. If children are skipped, the on_leave_children callback is still called.
virtual bool	on_leave_children (group_ptr g)
	called when the children of a group node g have been left, return whether to terminate traversal
virtual bool	on_enter_parent (node_ptr n)
	called before the parent of a node n is processed, return whether this should be skipped. If the parent is skipped, the on_leave_parent callback is still called.
virtual bool	on_leave_parent (node_ptr n)
	called when the parent of a node n has been left, return whether to terminate traversal

Member Function Documentation

on_enter_children()

bool cgv::base::traverse_callback_handler::on_enter_children ( group_ptr  g )

virtual

called before the children of a group node g are processed, return whether these should be skipped. If children are skipped, the on_leave_children callback is still called.

Definition at line 60 of file traverser.cxx.

on_enter_node()

bool cgv::base::traverse_callback_handler::on_enter_node ( base_ptr  b )

virtual

called before a node b is processed, return, whether to skip this node. If the node is skipped, the on_leave_node callback is still called

Definition at line 50 of file traverser.cxx.

on_enter_parent()

bool cgv::base::traverse_callback_handler::on_enter_parent ( node_ptr  n )

virtual

called before the parent of a node n is processed, return whether this should be skipped. If the parent is skipped, the on_leave_parent callback is still called.

Definition at line 70 of file traverser.cxx.

on_leave_children()

bool cgv::base::traverse_callback_handler::on_leave_children ( group_ptr  g )

virtual

called when the children of a group node g have been left, return whether to terminate traversal

Definition at line 65 of file traverser.cxx.

on_leave_node()

bool cgv::base::traverse_callback_handler::on_leave_node ( base_ptr  b )

virtual

called when a node b is left, return whether to terminate traversal

Definition at line 55 of file traverser.cxx.

on_leave_parent()

bool cgv::base::traverse_callback_handler::on_leave_parent ( node_ptr  n )

virtual

called when the parent of a node n has been left, return whether to terminate traversal
