Obtain or set the default state Passing a state name sets the default state
# File lib/celluloid/fsm.rb, line 28 def default_state(new_default = nil) if new_default @default_state = new_default.to_sym else defined?(@default_state) ? @default_state : DEFAULT_STATE end end
Declare an FSM state and optionally provide a callback block to fire Options:
to: a state or array of states this state can transition to
# File lib/celluloid/fsm.rb, line 44 def state(*args, &block) if args.last.is_a? Hash # Stringify keys :/ options = args.pop.inject({}) { |h,(k,v)| h[k.to_s] = v; h } else options = {} end args.each do |name| name = name.to_sym default_state name if options['default'] states[name] = State.new(name, options['to'], &block) end end
Obtain the valid states for this FSM
# File lib/celluloid/fsm.rb, line 37 def states @states ||= {} end
