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


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


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


Synthetic(int name_index,
          int length,
          ConstantPool constant_pool)
Construct object from file stream.

Method Detail


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


public final void dump( file)
Dump source file attribute to file stream in binary format.

public final byte[] getBytes()


public final void setBytes(byte[] bytes)


public final java.lang.String toString()
Description copied from class: java.lang.Object
Convert this Object to a human-readable String. There are no limits placed on how long this String should be or what it should contain. We suggest you make it as intuitive as possible to be able to place it into System.out.println() 55 and such.

It is typical, but not required, to ensure that this method never completes abruptly with a java.lang.RuntimeException.

This method will be called when performing string concatenation with this object. If the result is null, string concatenation will instead use "null".

The default implementation returns getClass().getName() + "@" + Integer.toHexString(hashCode()).
