public interface Measurable

extends Drawable

Title: Measurable Description: A Measurable object can return min and max values for its x and y extent. This interface is used to autoscale the x and y axes on a drawing panel. Minimum and maximum values may NOT be valid if isMeasured returns false. Objects that store data, for example, usually return zero if data is null. Copyright: Copyright (c) 2005

Method Summary

double	getXMax() Gets the maximum x needed to draw this object.
double	getXMin() Gets the minimum x needed to draw this object.
double	getYMax() Gets the maximum y needed to draw this object.
double	getYMin() Gets the minimum y needed to draw this object.
boolean	isMeasured() Determines if information is available to set min/max values.

Method Detail

getXMin

public double getXMin()

Gets the minimum x needed to draw this object.

Returns:

minimum

getXMax

public double getXMax()

Gets the maximum x needed to draw this object.

Returns:

maximum

getYMin

public double getYMin()

Gets the minimum y needed to draw this object.

Returns:

minimum

getYMax

public double getYMax()

Gets the maximum y needed to draw this object.

Returns:

minimum

isMeasured

public boolean isMeasured()

Determines if information is available to set min/max values. Objects that store data should return false if data is null.

Returns:

true if min/max values are valid
