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.- See Also:

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 contentsconstantPool
- The constant pool this attribute is associated with.

Synthetic
Synthetic(int nameIndex, int length, java.io.DataInput input, ConstantPool constantPool) throws java.io.IOException
Constructs object from input stream.- Parameters:
nameIndex
- Index in constant pool to CONSTANT_Utf8length
- Content length in bytesinput
- Input streamconstantPool
- Array of constants- Throws:
java.io.IOException
- if an I/O error occurs.
-
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.

-
copy
public Attribute copy(ConstantPool constantPool)
-
dump
public void dump(java.io.DataOutputStream file) throws java.io.IOException
Dump source file attribute to file stream in binary format.

getBytes
public byte[] getBytes()
- Returns:
- data bytes.
