40 * Dummy implementation of {@link DatatypeBuilder}.
41 *
42 * This implementation can be used for Datatypes which have no parameters.
43 * Any attempt to add parameters will be rejected.
44 *
45 * <p>
46 * Typical usage would be:
47 * <PRE><XMP>
48 * class MyDatatypeLibrary implements DatatypeLibrary {
49 *     ....
50 *     DatatypeBuilder createDatatypeBuilder( String typeName ) {
51 *         return new ParameterleessDatatypeBuilder(createDatatype(typeName));
52 *     }
53 *     ....
54 * }
55 * </XMP></PRE>
