# TDF_ChildIterator Class Reference

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".

## Public Member Functions

void * | operator new (size_t, void *anAddress)
void * | operator new (size_t size)
void | operator delete (void *anAddress)
Standard_EXPORT | TDF_ChildIterator ()
| Creates an empty iterator object to explore the children of a label. .
Standard_EXPORT | TDF_ChildIterator (const TDF_Label &aLabel, const Standard_Boolean allLevels=Standard_False)
| 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. .
Standard_EXPORT void | Initialize (const TDF_Label &aLabel, const Standard_Boolean allLevels=Standard_False)

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 <br> 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;
}
}
.

Standard_Boolean | More () const
| Returns true if a current label is found in the iteration process. .
Standard_EXPORT void | Next ()
| Move the current iteration to the next Item. .
Standard_EXPORT void | NextBrother ()

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.
.

const TDF_Label | Value () const
| Returns the current label; or, if there is none, a null label. .
