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 -- 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 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. fields myNode : TreeNode from TDataStd; myFirstLevel : Integer from Standard; end ChildNodeIterator;
