Structure form the TopoDS package.
An Explorer is built with :

Public Member Functions | |
DEFINE_STANDARD_ALLOC | TopExp_Explorer () |
Creates an empty explorer, becomes usefull after Init. | |
TopExp_Explorer (const TopoDS_Shape &S, const TopAbs_ShapeEnum ToFind, const TopAbs_ShapeEnum ToAvoid=TopAbs_SHAPE) | |
Creates an Explorer on the Shape <S>. <ToFind> is the type of shapes to search. TopAbs_VERTEX, TopAbs_EDGE, ... <ToAvoid> is the type of shape to skip in the exploration. If <ToAvoid> is equal or less complex than <ToFind> or if <ToAVoid> is SHAPE it has no effect on the exploration. | |
void | Init (const TopoDS_Shape &S, const TopAbs_ShapeEnum ToFind, const TopAbs_ShapeEnum ToAvoid=TopAbs_SHAPE) |
Resets this explorer on the shape S. It is initialized to search the shape S, for shapes of type ToFind, that are not part of a shape ToAvoid. If the shape ToAvoid is equal to TopAbs_SHAPE, or if it is the same as, or less complex than, the shape ToFind it has no effect on the search. | |
Standard_Boolean | More () const |
Returns True if there are more shapes in the exploration. | |
void | Next () |
Moves to the next Shape in the exploration. Exceptions Standard_NoMoreObject if there are no more shapes to explore. | |
const TopoDS_Shape & | Current () const |
Returns the current shape in the exploration. Exceptions Standard_NoSuchObject if this explorer has no more shapes to explore. | |
void | ReInit () |
Reinitialize the exploration with the original arguments. | |
Standard_Integer | Depth () const |
Returns the current depth of the exploration. 0 is the shape to explore itself. | |
void | Clear () |
Clears the content of the explorer. It will return False on More(). | |
void | Destroy () |
