//! If <allLevels> option is set to true,
//! it explores not only the first, but all the sub

//! If allLevels is false, only the first level of

//! In the example below, the label is iterated

//! void DumpChildren(const
//! TDF_Label& aLabel)
//! {
//! TDF_ChildIterator it;
//! TCollection_AsciiString es;
//! for
//! (it.Initialize(aLabel,Standard_True);

//! 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.
Standard_EXPORT void NextBrother() ;
