Member Function Documentation

bool TypeRegistryNode::check_derived_from (  const TypeRegistryNode *  child, const TypeRegistryNode *  base )  [static, private]

A recursive function to double-check the result of is_derived_from(). This is the slow, examine-the-whole-graph approach, as opposed to the clever and optimal algorithm of is_derived_from(); it's intended to be used only for debugging said clever algorithm. Definition at line 391 of file typeRegistryNode.cxx. Referenced by is_derived_from().

void TypeRegistryNode::clear_subtree (   )

Removes any subtree definition previously set up via define_subtree(), in preparation for rebuilding the subtree data. Definition at line 210 of file typeRegistryNode.cxx.

void TypeRegistryNode::define_subtree (   )

Indicates that this TypeRegistryNode is the top of a subtree within the inheritance graph (typically, this indicates a multiple-inheritance node). Builds all the subtree_mask etc. flags for nodes at this level and below. Definition at line 233 of file typeRegistryNode.cxx. Referenced by r_build_subtrees().

TypeHandle TypeRegistryNode::get_parent_towards (  const TypeRegistryNode *  child, const TypeRegistryNode *  base )  [static]

Returns the first parent class of child that is a descendant of the indicated base class. Definition at line 179 of file typeRegistryNode.cxx. Referenced by TypeRegistry::get_num_parent_classes().

bool TypeRegistryNode::is_derived_from (  const TypeRegistryNode *  child, const TypeRegistryNode *  base )  [static]

Returns true if the child RegistryNode represents a class that inherits directly or indirectly from the class represented by the base RegistryNode. Definition at line 55 of file typeRegistryNode.cxx. References TypeRegistryNode::Inherit::_bits, _inherit, TypeRegistryNode::Inherit::_mask, _name, TypeRegistryNode::Inherit::_top, check_derived_from(), nassertr, and NULL. Referenced by TypeRegistry::freshen_derivations().

void TypeRegistryNode::r_build_subtrees (  TypeRegistryNode *  top, int  bit_count, TypeRegistryNode::SubtreeMaskType  bits )  [private]

Recursively builds up all the subtree cache information for this node and the ones below. This information is used to quickly determine class inheritance. Definition at line 263 of file typeRegistryNode.cxx. References _inherit, _parent_classes, TypeRegistryNode::Inherit::_top, _top_inheritance, _visit_count, define_subtree(), nassertv, and NULL.
