Detailed Description

A helper ctree traversal class that maintains parent information.

Constructor & Destructor Documentation

ctree_parentee_t()

ctree_parentee_t::ctree_parentee_t ( bool post = false )

inline

Member Function Documentation

recalc_parent_types()

bool ctree_parentee_t::recalc_parent_types ( )

inline

Recalculate type of parent nodes.

If a node type has been changed, the visitor must recalculate all parent types, otherwise the ctree becomes inconsistent. If during this recalculation a parent node is added/deleted, this function returns true. In this case the traversal must be stopped because the information about parent nodes is stale.

Returns

false-ok to continue the traversal, true-must stop.
