getReferencePosition

public Position getReferencePosition()

Description copied from interface: Movable

A position associated with the object that indicates its aggregate geographic position. The chosen position varies among implementers of this interface. For objects defined by a list of positions, the reference position is typically the first position in the list. For symmetric objects the reference position is often the center of the object. In many cases the object's reference position may be explicitly specified by the application.

Parameters:

dc - the current drawing context.

shape - the surface shape to update.
