setup

public void setup(java.util.Collection<? extends LayoutNode> nodes,

                  java.awt.Rectangle rect)

Description copied from interface: ArchitectLayout

Sets up the layout algoritm. You have to call this before attempting to use an ArchitectLayout instance to perform a layout. TODO change the Rectangle into a point. This should indicate where to start but the layout should determine dimensions

Specified by:

setup in interface ArchitectLayout

Parameters:

nodes - The list of entities to be placed on
