final class OldRoutineType extends java.lang.Object implements Formatable
Class to simply read the old format written by DataTypeDescriptor prior to DERBY-2775 being addressed. The format was incorrect used in system catalogs for routine parameter and return types. The format contained repeated information. DERBY-2775 changed the code so that these catalog types were written as TypeDescriptor (which is what always had occurred for the types in SYSCOLUMNS).
