Interface TreeDef.Parented<T>

All Superinterfaces:

TreeDef<T>

Enclosing interface:

TreeDef<T>

public static interface TreeDef.Parented<T>
extends TreeDef<T>

A "doubly-linked" tree, where nodes know about both their parent and their children. It is CRITICAL that the TreeDef.Parented is consistent - if Vader claims that Luke and Leia are his children, then both Luke and Leia must say that Vader is their parent. If Luke or Leia don't agree that Vader is their father, then the algorithms that use this TreeDef.Parented are likely to fail in unexpected ways.
