Class CoordPoint.LongZM

java.lang.Object
  com.ibm.spatial.geom.CoordPoint
      com.ibm.spatial.geom.CoordPoint.Long
          com.ibm.spatial.geom.CoordPoint.LongZM

All Implemented Interfaces:

java.io.Serializable, java.lang.Cloneable

Enclosing class:

CoordPoint

public static class CoordPoint.LongZM
extends CoordPoint.Long

The LongZM class defines a CoordPoint specified in integer coordinates. Besides x and y, the point may have both a z coordinate and a measure.

CoordPoint.LongZM objects which don't have a z coordinate or a measure will have the corresponding fields initialized to java.lang.Long.MIN_VALUE. This is an implementation detail which may change in the future. The API users should use hasZ and hasM members in order to determine whether a CoordPoint.LongZM has a z coordinate or measure.
