public class LogicGate extends Transformer
Produce an output token on each firing with a value that is equal to the specified logic operator of the input(s). The functions are:
NOTE: All operators have a single input port, which is a multiport, and a single output port, which is not a multiport. All ports have type boolean.
This actor does not require that each input channel have a token upon firing. As long as one channel contains a token, output will be produced. If no input tokens are available at all, then no output is produced. At most one token is consumed on each input channel.
