All Implemented Interfaces:

Cloneable, Node

public final class Deprecated
extends Attribute

This class is derived from Attribute and denotes that this is a deprecated method. It is instantiated from the Attribute.readAttribute() method.

Deprecated_attribute {
    u2 attribute_name_index;
    u4 attribute_length;
}

Constructor Details

Deprecated

public Deprecated(Deprecated c)

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

Parameters:

c - Source to copy.

Deprecated

public Deprecated(int nameIndex,
 int length,
 byte[] bytes,
 ConstantPool constantPool)

Constructs a Deprecated attribute.

Parameters:

nameIndex - Index in constant pool to CONSTANT_Utf8.

length - JVM Specification: "The value of the attribute_length item must be zero.".

bytes - Attribute contents.

constantPool - Array of constants.

• JVM Specification: The Deprecated Attribute

Method Details

accept

public void accept(Visitor v)

Called by objects that are traversing the nodes of the tree implicitly defined by the contents of a Java class. That is, the hierarchy of methods, fields, attributes, and other elements forms a tree of objects.

Specified by:

accept in interface Node

Specified by:

accept in class Attribute

Parameters:

v - Visitor object.

copy

public Attribute copy(ConstantPool constantPool)

Description copied from class: Attribute

Creates a deep copy of this attribute.

Specified by:

copy in class Attribute

Parameters:

constantPool - constant pool to save.

Returns:

deep copy of this attribute.

getBytes

public byte[] getBytes()

Gets the data bytes.

Returns:

data bytes.

setBytes

public void setBytes(byte[] bytes)

Sets the data bytes.

Parameters:

bytes - The raw bytes that represents this byte array.

toString

public String toString()

Overrides:

toString in class Attribute

Returns:

attribute name.
