com.vividsolutions.jts.geom.impl.PackedCoordinateSequence
A {@link CoordinateSequence} implementation based on a packed arrays.In this implementation, {@link Coordinate}s returned by #toArray and #get are copies of the internal values. To change the actual values, use the provided setters.
For efficiency, created Coordinate arrays are cached using a soft reference. The cache is cleared each time the coordinate sequence contents are modified through a setter method. @version 1.7
