the class SimpleTypeBuilder method bindToTypeSafeEnum.

/**
 * Builds a type-safe enum conversion from a simple type
 * with enumeration facets.
 *
 * @param className
 *      The class name of the type-safe enum. Or null to
 *      create a default name.
 * @param javadoc
 *      Additional javadoc that will be added at the beginning of the
 *      class, or null if none is necessary.
 * @param members
 *      A map from enumeration values (as String) to BIEnumMember objects.
 *      if some of the value names need to be overrided.
 *      Cannot be null, but the map may not contain entries
 *      for all enumeration values.
 * @param loc
 *      The source location where the above customizations are
 *      specified, or null if none is available.
