org.aspectj.apache.bcel.classfile.Unknown
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. @version $Id: Unknown.java,v 1.6 2009/09/15 19:40:12 aclement Exp $ @see org.aspectj.apache.bcel.classfile.Attribute @author M.
