class ChildIterator from TDF
|
|
|
|
---Purpose: Iterates on the children of a label, at the first
|
|
-- level only. It is possible to ask the iterator to
|
|
-- explore all the sub label levels of the given one,
|
|
-- with the option "allLevels".

uses

Label from TDF,
|
|
LabelNodePtr from TDF

|
is
|
|
|
|
Create
|
|
returns ChildIterator from TDF;
|
|
---Purpose: Creates an empty iterator object to
|
|
-- explore the children of a label.
|
|
|
|
Create(aLabel : Label from TDF;
|
|
allLevels : Boolean from Standard = Standard_False)
|
|
returns ChildIterator from TDF;
|
|
---Purpose: Constructs the iterator object defined by
|
|
-- the label aLabel. Iterates on the children of the given label. If
|
|
-- <allLevels> option is set to true, it explores not
|
|
-- only the first, but all the sub label levels.
|
|
|
|
Initialize(me : in out;
|
|
aLabel : Label from TDF;
|
|
allLevels : Boolean from Standard = Standard_False);
|
|
---Purpose: Initializes the iteration on the children of the
|
|
-- given label.
|
|
-- If <allLevels> option is set to true,
|
|
-- it explores not only the first, but all the sub
|
|
-- label levels.
|
|
-- If allLevels is false, only the first level of
|
|
-- child labels is explored.
|
|
-- In the example below, the label is iterated
|
|
-- using Initialize, More and Next and its
|
|
-- child labels dumped using TDF_Tool::Entry.
|
|
-- Example
|
|
-- void DumpChildren(const
|
|
-- TDF_Label& aLabel)
|
|
-- {
|
|
-- TDF_ChildIterator it;
|
|
-- TCollection_AsciiString es;
|
|
-- for
|
|
-- (it.Initialize(aLabel,Standard_True);
|
|
-- it.More(); it.Next()){
|
|
-- TDF_Tool::Entry(it.Value(),es);
|
|
-- cout << as.ToCString() << endl;
|
|
-- }
|
|
-- }
|
|
More(me) returns Boolean;
|
|
---Purpose: Returns true if a current label is found in the
|
|
-- iteration process.
|
|
--
|
|
---C++: inline
|
|
|
|
Next(me : in out);
|
|
---Purpose: Move the current iteration to the next Item.
|
|
|
|
NextBrother(me : in out);
|
|
---Purpose: Moves this iteration to the next brother
|
|
-- label. A brother label is one with the same
|
|
-- father as an initial label.
|
|
-- Use this function when the non-empty
|
|
-- constructor or Initialize has allLevels set to
|
|
-- true. The result is that the iteration does not
|
|
-- explore the children of the current label.
|
|
-- This method is interesting only with
|
|
-- "allLevels" behavior, because it avoids to explore
|
|
-- the current label children.
|
|
|
|
Value(me) returns Label from TDF;
|
|
---Purpose: Returns the current label; or, if there is
|
|
-- none, a null label.
