public abstract class PlacementInfo

extends java.lang.Object

This class is the superclass for libraries that implement placement

Field Summary

protected int	height Placement size
protected java.lang.String	transformations Any placement should modify this, as it determines the uniqueness of a cell type
static int	UNCONSTRAINED A constant meaning unplaced
protected int	width Placement size
protected int	x Placement coordinate
protected int	y Placement coordinate

Constructor Summary

PlacementInfo()
Create an unconstrained placement

PlacementInfo(int x, int y)
Create a placement at x, y

Method Summary

void	appendTransformation(java.lang.String transform) Add the latest transformation onto the transformation status string
int	getHeight() Return the height
java.lang.String	getTransformation(Cell c) Return the transformation
int	getWidth() Return the width
int	getX() Return the x coordinate
int	getY() Return the y coordinate
