public static class CoordPoint.DoubleZM
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.
