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 final 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 final byte[] getBytes()
Returns:
data bytes.

setBytes

public final void setBytes(byte[] bytes)

toString

public final 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
