Detailed Description
A helper ctree traversal class that maintains parent information.
- Examples
- hexrays_sample5.cpp.

Constructor & Destructor Documentation
◆ ctree_parentee_t()
| ctree_parentee_t::ctree_parentee_t | ( | bool | post = false | ) |
Definition at line 5896 of file hexrays.hpp.
Member Function Documentation
◆ get_block()
| cblock_t * ctree_parentee_t::get_block | ( | ) |
Get pointer to the parent block of the currently visited item.
This function should be called only when the parent is a block.
Definition at line 7309 of file hexrays.hpp.
References cinsn_t::cblock, cit_block, citem_t::op, and ctree_visitor_t::parents.
◆ recalc_parent_types()
| bool ctree_parentee_t::recalc_parent_types | ( | ) |
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.
