Detailed Description

template<typename TYPE>
class occ::down_cast< TYPE >

Downcasting operator for OpenCascade handles.

It wraps up into a syntactic C++ sugar the way casting of handles is supported in OpenCascade

Example : suppose you would like to downcast an Handle_Geom_Curve into a Handle_Geom_Circle. With OpenCascade it can be done by :

Handle_Geom_Circle gcircle = Handle_Geom_Circle::DownCast(gcurve);

The equivalent with the down_cast<> operator is :

Handle_Geom_Circle gcircle = occ::down_cast<Handle_Geom_Circle>(gcurve);
