com.vividsolutions.jts.geom.impl.CoordinateArraySequence
The {@link CoordinateSequence} implementation that {@link 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
