org.aspectj.apache.bcel.classfile.Unknown

All Implemented Interfaces:

Serializable, Cloneable, Node

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 Details

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.

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
