restore() [1/2]

void flutter::RectBoundsAccumulator::restore ( )

overridevirtual

Restore to the previous accumulation and incorporate the bounds of the primitives that were recorded since the last save (if needed).

Implements flutter::BoundsAccumulator.

Definition at line 20 of file dl_bounds_accumulator.cc.

                                    {

save()

void flutter::RectBoundsAccumulator::save ( )

overridevirtual

Save aside the rects/bounds currently being accumulated and start accumulating a new set of rects/bounds. When restore is called, some additional modifications may be applied to these new bounds before they are accumulated back into the surrounding bounds.

Implements flutter::BoundsAccumulator.

Definition at line 16 of file dl_bounds_accumulator.cc.
