public final Class Unknown

extends Attribute
Class Inheritance
Imports
java.io.DataInputStream, .DataOutputStream, .IOException, org.aspectj.apache.bcel.Constants
This class represents a reference to an unknown (i.e., application-specific) attribute of a class. It is instantiated from the Attribute.readAttribute() method. Applications that need to read in application-specific attributes should create an AttributeReader implementation and attach it via Attribute.addAttributeReader.
