- All Implemented Interfaces: 
- java.lang.Cloneable, Node, java.io.Serializable
- public final class Unknown- extends Attribute
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.

Unknown
public Unknown(Unknown c)
- Initialize from another object. Note that both objects use the same
 references (shallow copy). Use clone() for a physical copy.
 
Unknown
public Unknown(int name_index,
               int length,
               byte[] bytes,
               ConstantPool constant_pool)
- Create a non-standard attribute.
 
- Parameters:
- name_index- Index in constant pool
- length- Content length in bytes
- bytes- Attribute contents
- constant_pool- Array of constants
accept
public void accept(Visitor v)
- Called by objects that are traversing the nodes of the tree implicitely
 defined by the contents of a Java class. I.e., the hierarchy of methods,
 fields, attributes, etc. spawns a tree of objects.
