static member GetDescendants :
node : 'T *
getChildren : Func<'T, IEnumerable<'T>> -> IEnumerable<'T> when 'T : not struct
Parameters
- node
- Type: T
The reference node where to start the search. (The reference node will not be included in
the enumeration.)
- getChildren
- Type: SystemFuncT, IEnumerableT
A method that retrieves the children of an object of type T.
GetDescendantsT(T, FuncT, IEnumerableT) guarantees that
getChildren is never called with as parameter. The
enumeration returned by getChildren may contain .
Type Parameters
- T
- The type of node that is enumerated.
Return Value
Type:
IEnumerableTThe descendants of
node.
Exceptions Remarks
This method can be used to traverse a tree in depth-first order (preorder).
