Validate

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

Validate
The Validate method subtracts the specified area from the update shape for this canvas.
void Validate (in ODShape shape);
shape
A reference to the shape object defining the area to subtract from the update shape for this canvas.

DISCUSSION
OpenDoc calls this method internally to mark an area of a canvas that no longer needs updating. Your part typically calls its facet's Validate method instead of this method because that method transforms and clips the shape from the coordinate space of the facet to the coordinate space of its canvas.
