Validate

Inside Macintosh: OpenDoc Class Reference /: Part 1 - Classes and Methods / ODFacet

Validate
The Validate method marks the specified area in this facet as no longer in need of updating.
void Validate (in ODShape validShape, 
               in ODCanvas biasCanvas);
validShape
A reference to a shape object defining the area in this facet that no longer needs updating, expressed in frame coordinates.
biasCanvas
kODNULL if the geometry is in platform-normal coordinates, otherwise a reference to the canvas object to whose coordinate space the geometry is biased.

DISCUSSION
OpenDoc calls this method. This method transforms and clips the shape from the coordinate space of this facet to the coordinate space of its canvas. It then subtracts the shape from any existing invalid area of the canvas.
