Package org.apache.bcel.classfile

Class Synthetic

java.lang.Object

org.apache.bcel.classfile.Attribute

org.apache.bcel.classfile.Synthetic

All Implemented Interfaces:

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 Details

Synthetic

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

Parameters:

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

length - Content length in bytes - should be zero.

bytes - Attribute contents

constantPool - The constant pool this attribute is associated with.

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.

Parameters:

c - Source to copy.

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. 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

copy

public Attribute copy(ConstantPool constantPool)

Specified by:

copy in class Attribute

Parameters:

constantPool - constant pool to save.

Returns:

deep copy of this attribute

dump

public void dump(DataOutputStream file)
          throws IOException

Dump source file attribute to file stream in binary format.

Overrides:

dump in class Attribute

Parameters:

file - Output file stream

Throws:

IOException - if an I/O error occurs.

getBytes

public byte[] getBytes()

Returns:

data bytes.

setBytes

public void setBytes(byte[] bytes)

Parameters:

bytes -

toString

public String toString()

Overrides:

toString in class Attribute

Returns:

String representation.
