class ChildNodeIterator from TDataStd
---Purpose: Iterates on the ChildStepren step of a step, at the
-- first level only. It is possible to ask the
-- iterator to explore all the sub step levels of the
-- given one, with the option "allLevels".
uses TreeNode from TDataStd
is
Create
returns ChildNodeIterator from TDataStd;
---Purpose: Creates an empty iterator.
Create(aTreeNode : TreeNode from TDataStd;
allLevels : Boolean from Standard = Standard_False)
returns ChildNodeIterator from TDataStd;
---Purpose: Iterates on the ChildStepren of the given Step. If
-- <allLevels> option is set to true, it explores not
-- only the first, but all the sub Step levels.
Initialize(me : in out;
aTreeNode : TreeNode from TDataStd;
allLevels : Boolean from Standard = Standard_False);
---Purpose: Initializes the iteration on the Children Step of
-- the given Step. If <allLevels> option is set to
-- true, it explores not only the first, but all the
-- sub Step levels.
More(me) returns Boolean;
---C++: inline
---Purpose: Returns True if there is a current Item in the
-- iteration.
Next(me : in out);
---Purpose: Move to the next Item
NextBrother(me : in out);
---Purpose: Move to the next Brother. If there is none, go up
-- etc. This method is interesting only with
-- "allLevels" behavior, because it avoids to explore
-- the current Step ChildStepren.
Value(me) returns TreeNode from TDataStd;
---C++: inline
---Purpose: Returns the current item; a null Step if there is
-- no one.
