Base class for Tree nodes.
All nodes of a tree inherit from this type. The main features that this class provides are:
children
data member that enumerates the nodes pointed to by the ChildEdge data members. This list of all children is updated automatically as assignments are made to the ChildEdge data members.parent
data member that points to the parent node in the tree, or null if this node is the root of a tree. The parent pointers are updated automatically as nodes are inserted into and removed from the tree.std::shared_ptr
, and node memory is reclaimed automatically when there are no more references to the node, either as parentchild edges or other shared pointers outside the tree's control. The pointers from child to parent within the tree data structure itself are weak and do not count as references to the parent node.#include <Tree.h>

Traverse the tree starting at this node and following child pointers.
The functor
takes two arguments: the tree node under consideration, and a TraversalEvent that indicates whether the traversal is entering or leaving the node. The functor must return a TraversalAction to describe what should happen next.
If the functor called by the node enter event returns SKIP_CHILDREN, then none of the children are traversed and the next call to the functor is for leaving that same node.
If any call to the functor returns ABORT, then the traversal is immediately aborted.
If any functor returns ABORT, then the traverse function also returns ABORT. Otherwise the traverse function returns CONTINUE.
