org.geotools.referencing.factory.AbstractAuthorityFactory
psg.org">European Petroleum Survey Group (EPSG) maintains a database of coordinate systems, and other spatial referencing objects, where each object has a code number ID. For example, the EPSG code for a WGS84 Lat/Lon coordinate system is {@code "4326"}.
This class defines a default implementation for most methods defined in the {@link DatumAuthorityFactory}, {@link CSAuthorityFactory} and {@link CRSAuthorityFactory}interfaces. However, those interfaces do not appear in the {@code implements} clause ofthis class declaration. This is up to subclasses to decide which interfaces they declare to implement.
The default implementation for all {@code createFoo} methods ultimately invokes{@link #createObject}, which may be the only method that a subclass need to override. However, other methods may be overridden as well for better performances. @since 2.1 @source $URL$ @version $Id$ @author Martin Desruisseaux (IRD)

     * The objects found are expected to be cached.
