Class PrecisionPointList

java.lang.Object

org.eclipse.draw2d.geometry.PointList

org.eclipse.draw2d.geometry.PrecisionPointList

All Implemented Interfaces:

Serializable, Translatable

public final class PrecisionPointList
extends PointList

A PointList implementation using floating point values which are truncated into the inherited integer fields. The use of floating point prevents rounding errors from accumulating. EXPERIMENTAL This class has been added as part of a work in progress and there is no guarantee that this API will remain unchanged. This is likely to not function properly outside some very specific use-cases.

Since:

3.21
