Method Detail

contains

public boolean contains(Point center,
               Point point)

draw

public void draw(BoundingBox boundingBox,
        byte zoomLevel,
        Canvas canvas,
        Point topLeftPoint)

Description copied from class: Layer

Draws this Layer on the given canvas.

Specified by:

draw in class Layer

Parameters:

boundingBox - the geographical area which should be drawn.

zoomLevel - the zoom level at which this Layer should draw itself.
