## com.vividsolutions.jts.geom.impl
Class CoordinateArraySequence

    java.lang.Object
      com.vividsolutions.jts.geom.impl.CoordinateArraySequence

All Implemented Interfaces:
  java.lang.Cloneable, CoordinateSequence, java.io.Serializable

public class CoordinateArraySequence
extends java.lang.Object
implements CoordinateSequence, java.io.Serializable

The `CoordinateSequence` implementation that `Geometry`s use by default. In this implementation, Coordinates returned by #toArray and #getCoordinate are live -- modifications to them are actually changing the CoordinateSequence's underlying data.

Version:
  1.7
