Interface DatumFactory

All Superinterfaces:
Factory, ObjectFactory
@UML(identifier="CS_CoordinateSystemFactory", specification=OGC_01009) public interface DatumFactory extends ObjectFactory
Builds up complex datums from simpler objects or values. DatumFactory allows applications to make datums that cannot be created by a DatumAuthorityFactory. This factory is very flexible, whereas the authority factory is easier to use. So DatumAuthorityFactory can be used to make "standard" datums, and DatumFactory can be used to make "special" datums.
