Package org.apache.bcel.classfile

Class Synthetic

java.lang.Object

org.apache.bcel.classfile.Attribute

org.apache.bcel.classfile.Synthetic

All Implemented Interfaces:

java.lang.Cloneable, Node

public final class Synthetic
extends Attribute

This class is derived from Attribute and declares this class as `synthetic', i.e., it needs special handling. The JVM specification states "A class member that does not appear in the source code must be marked using a Synthetic attribute." It may appear in the ClassFile attribute table, a field_info table or a method_info table. This class is intended to be instantiated from the Attribute.readAttribute() method.

Constructor Detail

Synthetic

public Synthetic(Synthetic c)

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

Synthetic

public Synthetic(int name_index,
                 int length,
                 byte[] bytes,
                 ConstantPool constant_pool)

Parameters:

name_index - Index in constant pool to CONSTANT_Utf8, which should represent the string "Synthetic".

length - Content length in bytes - should be zero.

bytes - Attribute contents

constant_pool - The constant pool this attribute is associated with.

Method Detail

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.

Specified by:

accept in interface Node

Specified by:

accept in class Attribute

Parameters:

v - Visitor object

dump

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

Dump source file attribute to file stream in binary format.

Overrides:

dump in class Attribute

Parameters:

file - Output file stream

Throws:

java.io.IOException

getBytes

public byte[] getBytes()

Returns:

data bytes.

setBytes

public void setBytes(byte[] bytes)

Parameters:

bytes -

toString

public java.lang.String toString()

Overrides:

toString in class Attribute

Returns:

String representation.

copy

public Attribute copy(ConstantPool _constant_pool)

Specified by:

copy in class Attribute

Returns:

deep copy of this attribute
