        dc - the current draw context.

      • drawOrderedRenderable

        protected void drawOrderedRenderable​(DrawContext dc)

        protected void endDrawing​(DrawContext dc)
        Pop the state set in beginDrawing.
        Parameters:
        dc - the current draw context.

      • doDrawOrderedRenderable

        protected void doDrawOrderedRenderable​(DrawContext dc)
