Class CoordPoint.DoubleZM

java.lang.Object
  com.ibm.spatial.geom.CoordPoint
      com.ibm.spatial.geom.CoordPoint.Double
          com.ibm.spatial.geom.CoordPoint.DoubleZM

All Implemented Interfaces:

java.io.Serializable, java.lang.Cloneable

Enclosing class:

CoordPoint

public static class CoordPoint.DoubleZM
extends CoordPoint.Double

The CoordPoint.DoubleZM class defines a CoordPoint specified in double precision coordinates. Besides x and y, the point may have a z coordinate and a measure.

CoordPoint.DoubleZM objects which don't have a z coordinate or a measure will have the corresponding fields initialized to java.lang.Double.NaN. 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.DoubleZM has a z coordinate or measure.
