      org.multijava.util.classfile.UniverseFieldAttribute

public class UniverseFieldAttribute

extends Attribute

This class implements a JUTS field attribute. It is basically just a wrapper for one byte that describes the universe type modifier for a field of reference or array type. The format of the attribute (not including the standard initial six bytes): - the one and only byte is the encoded universe type modifier for this field This attribute is recognized by UniverseAttributeParser. VMS 4.7.1: The attribute's name is org.multijava.universe_field
