## org.apache.bcel.classfile
Class Synthetic

    java.lang.Object
      org.apache.bcel.classfile.Attribute
          org.apache.bcel.classfile.Synthetic

All Implemented Interfaces:
  Serializable, 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 final 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`

### getBytes

    public final byte[] getBytes()

  Returns:
    data bytes.

### setBytes

    public final void setBytes(byte[] bytes)

  Parameters:
    `bytes` -

### toString

    public final 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
