- 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 poollength
- Content length in bytesbytes
- Attribute contentsconstant_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.
