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". More...

TDF_ChildIterator () | |
Creates an empty iterator object to explore the children of a label. More... | |
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. More... | |
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 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... | |
Standard_Boolean | More () const |
Returns true if a current label is found in the iteration process. More... | |
void | Next () |
Move the current iteration to the next Item. More... | |
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. More... | |
const TDF_Label | Value () const |
Returns the current label; or, if there is none, a null label. More... | |

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

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