_NodePtr algorithms
|
|
|
|
The algorithms taking _NodePtr are red black tree algorithms. Those
|
|
algorithms taking a parameter named __root should assume that __root
|
|
points to a proper red black tree (unless otherwise specified).
|
|
|
|
Each algorithm herein assumes that __root->__parent_ points to a non-null
|
|
structure which has a member __left_ which points back to __root. No other
|
|
member is read or written to at __root->__parent_.
|
|
|
|
__root->__parent_ will be referred to below (in comments only) as end_node.
|
|
end_node->__left_ is an externably accessible lvalue for __root, and can be
|
|
changed by node insertion and removal (without explicit reference to end_node).
|
|
|
|
All nodes (with the exception of end_node), even the node referred to as
|
|
__root, have a non-null __parent_ field.
