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.

Attribute

Variable Index

o bytes
o constant_pool
o name
o unknown_attributes

Constructor Index

o Unknown()
Empty constructor, all attributes have to be defined via `setXXX' methods.
o Unknown(int, int, byte[], ConstantPool)
Create a non-standard attribute.
o Unknown(int, int, DataInputStream, ConstantPool)
Construct object from file stream.
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 getUnknownAttributes()
o setBytes(byte[])
o setConstantPool(ConstantPool)
o toString()

Variables

o bytes 
 private byte bytes[]
o constant_pool 
 private ConstantPool constant_pool
o name 
 private String name
o unknown_attributes 
 private static Hashtable unknown_attributes

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(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
o Unknown 
 Unknown(int name_index,
         int length,
         DataInputStream file,
         ConstantPool constant_pool) throws IOException
Construct object from file stream.

Parameters:
name_index - Index in constant pool
length - Content length in bytes
file - Input stream
constant_pool - Array of constants

Methods

o getUnknownAttributes 
 static Unknown[] getUnknownAttributes()
Returns:
array of unknown attributes, but just one for each kind.
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
