version
- the class version. The minor version is stored in the 16 most significant bits,
and the major version in the 16 least significant bits.access
- the class's access flags (see Opcodes
). This parameter also indicates if
the class is deprecated.name

).signature
- the signature of this class. May be null if the class is not a
generic one, and does not extend or implement generic classes or interfaces.supername
- the internal of name of the super class (see Type.getInternalName()
).
For interfaces, the super class is Object
. May be null, but only for the
