public final class Unknown
extends Attribute
This class is derived from Attribute and represents a reference to an unknown (i.e. unimplemented) attribute of this class. It is instantiated from the Attribute.readAttribute() method.

Constructor Index

 o Unknown()
Empty constructor, all attributes have to be defined via `setXXX' methods.
 o Unknown(short, int, byte[], ConstantPool)
Create a non-standard attribute.
 o Unknown(Unknown)
Initialize from another object.

Method Index

 o accept(Visitor)
Called by objects that are traversing the nodes of the tree implicitely defined by the contents of a Java class.
 o dump(DataOutputStream)
Dump unknown bytes to file stream.
 o getBytes()
 o getConstantPool()
 o getName()
 o setBytes(byte[])
 o setConstantPool(ConstantPool)
 o toString()

Constructors

 o Unknown
 public Unknown()
Empty constructor, all attributes have to be defined via `setXXX' methods. Use at your own risk.

 o 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.

 o Unknown
 public Unknown(short 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

Methods

 o 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.

Parameters:
v - Visitor object
Overrides:
accept in class Attribute
 o dump
 public final void dump(DataOutputStream file) throws IOException
Dump unknown bytes to file stream.

Parameters:
file - Output file stream
Overrides:
dump in class Attribute
 o getBytes
 public final byte[] getBytes()
Returns:
data bytes.
 o getName
 public final String getName()
Returns:
name of attribute.
 o getConstantPool
 public final ConstantPool getConstantPool()
Returns:
Constant pool used by this object.
See Also:
ConstantPool
 o setBytes
 public final void setBytes(byte bytes[])
 o setConstantPool
 public final void setConstantPool(ConstantPool constant_pool)
Parameters:
constant_pool - Constant pool to be used for this object.
See Also:
ConstantPool
 o toString
 public final String toString()
Returns:
String representation.
Overrides:
toString in class Object
