Class Reflector

java.lang.Object
  Reflector

public class Reflector
extends java.lang.Object

A Reflector is a device of an enigma machine that is used to swap the values between pairs of letters according to the way its wires are setup. This implementation provides 2 types of reflectors B and C representing the possible reflectors used in the enigma M3 machine. It is called reflector because letters are permuted in pairs (for example, in reflector type B you noticed that an entering letter 'A' gets changed to letter 'Y' and an entering letter 'Y' gets changed to letter 'A')
