| elements | () | method |
public static function elements(hierarchy:INodeHierarchy):IterableReturns all elements that are part of the hierarchy.
Parameters
hierarchy:INodeHierarchy — The hierarchy itself.
|
Iterable — An enumeration of the contents of the hierarchy at the time of this invokation.
|
| getDescendants | () | method |
public static function getDescendants(hierarchy:INodeHierarchy, root:INode):IterableReturns all descendants of the provided item that are part of the hierarchy.
The enumeration will be top down, i.e. all of an item's ancestors will be enumerated before the respective item.
Parameters
hierarchy:INodeHierarchy — The hierarchy itself.
| |
root:INode — The root item to get the descendants from.
|
Iterable — An enumeration of the children of the item at the time of this invocation
in reverse dfs prefix order.
|
| getDescendantsBottomUp | () | method |
public static function getDescendantsBottomUp(hierarchy:INodeHierarchy, root:INode):IterableReturns all descendants of the provided item that are part of the hierarchy.
The iteration will be bottom up, i.e. all of an item's children will be iterated before the respective item.
Parameters
hierarchy:INodeHierarchy — The hierarchy itself.
| |
root:INode — The root item to get the descendants from.
|
Iterable — An iterable of the children of the item at the time of this invokation in dfs postfix order.
|
| getNearestCommonAncestor | () | method |
public static function getNearestCommonAncestor(hierarchy:INodeHierarchy, items:Iterator):INodeDetermines the nearest common ancestor of the items provided in the hierarchy.
Parameters
hierarchy:INodeHierarchy — The hierarchy itself.
| |
items:Iterator — The items to find the nearest common ancestor of
|
INode |
| getPathToRoot | () | method |
public static function getPathToRoot(hierarchy:INodeHierarchy, node:INode):IterableGets the path to root traversing all parents of the given item.
Parameters
hierarchy:INodeHierarchy — The hierarchy to use for retrieving the parents.
| |
node:INode — The node to start.
|
Iterable — A list that includes the node but not the root, unless they are identical and all
parents in between them.

node:INode — The node to check.
| |
parent:INode — The parent to check.
