Class MultiThrottle

java.lang.Object

jmri.jmrit.withrottle.MultiThrottle

public class MultiThrottle
extends Object

Keeps track of what locos are being controlled by a throttle, and passes the control messages on to them. Creates a new MultiThrottleController for each loco requested on this throttle. Each loco will then be able to be controlled individually. '*' is a wildcard loco key. Forwards to all locos on this MultiThrottle.

Sample messages:

• MT+L757<;>L757 On T throttle, add loco L757.
• MT+L1234<;>L1234 On T throttle, add loco L1234.
• MTSL1234<;>L1234 On T throttle, steal loco L1234.
• MTAL757<;>R1 On T throttle, loco L757, set direction to forward.
• MTAL1234<;>R0 On T throttle, loco L1234, set direction to reverse.
• MTAL757<;>V42 On T throttle, loco L757, set speed to 42.
• MTAL1234<;>V42 On T throttle, loco L1234, set speed to 42.
• MTA*<;>V16 On T throttle, all locos, set speed to 16.
• MT-L757<;>L757 On T throttle, remove loco L757. (Still has L1234)
