Expand description
Wrapper around indices to the collection of nodes inside a Tree
.
Returns the index of the root node.
Returns the index of the node to the left of the current one.
Returns the index of the node to the right of the current one.
Returns the index of the parent node or None
if current node is the root.
Returns the number of nodes leading from the root to the current node, including self
.

This method tests for self
and other
values to be equal, and is used
by ==
.
This method tests for !=
. The default implementation is almost always
sufficient, and should not be overridden without very good reason.
