virtual bool SkPicture::AbortCallback::abort ( )

pure virtual

Stops SkPicture playback when some condition is met.

A subclass of AbortCallback provides an override for abort() that can stop SkPicture::playback.

The part of SkPicture drawn when aborted is undefined. SkPicture instantiations are free to stop drawing at different points during playback.

If the abort happens inside one or more calls to SkCanvas::save(), stack of SkCanvas matrix and SkCanvas clip values is restored to its state before SkPicture::playback was called.
