Detailed Description

A helper ctree traversal class that maintains parent information.

Examples
hexrays_sample5.cpp.

Definition at line 5837 of file hexrays.hpp.

Constructor & Destructor Documentation

◆ ctree_parentee_t()

ctree_parentee_t::ctree_parentee_t ( bool  post = false)

Definition at line 5839 of file hexrays.hpp.

Member Function Documentation

◆ get_block()

cblock_t * ctree_parentee_t::get_block ( void  )

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 7215 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 ( void  )

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.
