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.

Constructor Detail


public Unknown(Unknown c)
Initialize from another object. Note that both objects use the same references (shallow copy). Use clone() for a physical copy.


public Unknown(int name_index,
               int length,
               byte[] bytes,
               ConstantPool constant_pool)
Create a non-standard attribute.


Unknown(int name_index,
        int length, file,
        ConstantPool constant_pool)
Construct object from file stream.

Method Detail


static Unknown[] getUnknownAttributes()


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.

Specified by:
accept in interface Node
Specified by:
accept in class Attribute


public final void dump( file)
Dump unknown bytes to file stream.

public final byte[] getBytes()


public final java.lang.String getName()


public final void setBytes(byte[] bytes)


public final java.lang.String toString()
Description copied from class: java.lang.Object
Convert this Object to a human-readable String. There are no limits placed on how long this String should be or what it should contain. We suggest you make it as intuitive as possible to be able to place it into System.out.println() 55 and such.

It is typical, but not required, to ensure that this method never completes abruptly with a java.lang.RuntimeException.

This method will be called when performing string concatenation with this object. If the result is null, string concatenation will instead use "null".

The default implementation returns getClass().getName() + "@" + Integer.toHexString(hashCode()).
