Examples of GeneralDirectPosition

org.apache.sis.geometry.GeneralDirectPosition
Holds the coordinates for a position within some coordinate reference system. Since {@code DirectPosition}s, as data types, will often be included in larger objects (such as {@linkplain org.opengis.geometry.Geometry geometries}) that have references to {@code CoordinateReferenceSystem}, the {@link #getCoordinateReferenceSystem()} methodmay returns {@code null} if this particular {@code DirectPosition} is included in suchlarger object. In this case, the coordinate reference system is implicitly assumed to take on the value of the containing object's {@code CoordinateReferenceSystem}.
This particular implementation of {@code DirectPosition} is said "General" because ituses an {@linkplain #ordinates array of ordinates} of an arbitrary length. If the directposition is known to be always two-dimensional, then {@link DirectPosition2D} providesa more efficient implementation.
