Module org.jhotdraw8.geom

Package org.jhotdraw8.geom

Class AreaMetricsBuilder

java.lang.Object

org.jhotdraw8.geom.AbstractPathBuilder<Double>

org.jhotdraw8.geom.AreaMetricsBuilder

All Implemented Interfaces:

PathBuilder<Double>

public class AreaMetricsBuilder
extends AbstractPathBuilder<Double>

Computes the area of a path. This only makes sense for closed paths.

FIXME implement doCurveTo and doQuadTo

XXX Only works with consolidated inputs, for example from a Area object
