Detailed Description

This class is the base class for custom GsNode objects which implement custom caching support for Teigha vectorization applications.

Remarks: Cached rendering information may be stored in a custom GsNode descendant for each drawable in an OdDbDatabase object.

This cached information can be fed into the Teigha vectorization framework during a redraw instead of making the usual calls to subWorldDraw() and subViewportDraw(), thereby greatly improving the speed of redraws.

Remarks: Clients should derive their custom node classes from this class.

Corresponding C++ library: TD_Gs <group OdGs_Classes>
