Constructor Detail

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.

               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

Method Detail

accept

public void accept(Visitor v)

dump

public final void dump(java.io.DataOutputStream file)
                throws java.io.IOException

Dump unknown bytes to file stream.

Overrides:

dump in class Attribute

Parameters:

file - Output file stream

getBytes

public final byte[] getBytes()

Returns:

data bytes.

getName

public final java.lang.String getName()

Returns:

name of attribute.

setBytes

public final void setBytes(byte[] bytes)

Parameters:

bytes. -

toString

public final java.lang.String toString()

Overrides:

toString in class Attribute

Returns:

String representation.

copy

public Attribute copy(ConstantPool constant_pool)

Overrides:

copy in class Attribute

Returns:

deep copy of this attribute
