Detailed Description

Iterates over subshapes in a shape.

Iterator supports two usage scenario:

• iteration over direct children;
• iteration over subshapes of a specified type.

Exploration of Direct Children

To retrive direct children of a shape, ModelData.ShapeIterator should be used as follows:

ModelData::Wire aWire = ...;
ModelData::ShapeIterator i (aWire);
while (i.HasNext()) {
    const ModelData::Shape& aChild = i.Next(); //edge
    ModelData::ShapeType aType = aChild.Type();
    assert (aType == ModelData::ShapeType::Edge);
}

Exploration of particular types

To retrive children of a particular type, ModelData.ShapeIterator should be used by specifying a type of interest as follows:

ModelData::Solid aSolid = ...;
ModelData::ShapeIterator i (aSolid, ModelData::ShapeType_Edge); //iterate over edges in the solid
while (i.HasNext()) {
    ModelData::Shape aChild = i.Next();
    const ModelData::Edge& anEdge = static_cast<const ModelData::Edge&> (aChild); //edge
    ...
}

When using the latter approach exploration is done traversing the graph of subshapes in a depth-first manner. Each subshape will be found as many times as it is registered in the parent subshape. For instance, a seam-edge will be encountered twice, with forward and reversed orientations.

The order of returned subshapes is deterministic and corresponds to the order in which the subshapes were added during construction.
