The builder module used to declare superstates.
| subject | [R] |
Used to specify the default state held by the history pseudo state of the superstate.
sm = Statemachine.build do
superstate :operational do
default_history :state_id
end
end
# File lib/statemachine/builder.rb, line 215
215: def default_history(id)
216: @subject.default_history = id
217: end
Allows the declaration of entry actions without using the state method. id is identifies the state to which the entry action will be added.
sm = Statemachine.build do
trans :locked, :coin, :unlocked
on_entry_of :unlocked, :unlock
end
# File lib/statemachine/builder.rb, line 191
191: def on_entry_of(id, action)
192: @statemachine.get_state(id).entry_action = action
193: end
Allows the declaration of exit actions without using the state method. id is identifies the state to which the exit action will be added.
sm = Statemachine.build do
trans :locked, :coin, :unlocked
on_exit_of :locked, :unlock
end
# File lib/statemachine/builder.rb, line 203
203: def on_exit_of(id, action)
204: @statemachine.get_state(id).exit_action = action
205: end
Specifies the startstate for the statemachine or superstate. The state must exist within the scope.
sm = Statemachine.build do
startstate :locked
end
# File lib/statemachine/builder.rb, line 179
179: def startstate(startstate_id)
180: @subject.startstate_id = startstate_id
181: end
Define a state within the statemachine or superstate.
sm = Statemachine.build do
state :locked do
#define the state
end
end
# File lib/statemachine/builder.rb, line 131
131: def state(id, &block)
132: builder = StateBuilder.new(id, @subject, @statemachine)
133: builder.instance_eval(&block) if block
134: end
Define a superstate within the statemachine or superstate.
sm = Statemachine.build do
superstate :operational do
#define superstate
end
end
# File lib/statemachine/builder.rb, line 144
144: def superstate(id, &block)
145: builder = SuperstateBuilder.new(id, @subject, @statemachine)
146: builder.instance_eval(&block)
147: end
Declares a transition within the superstate or statemachine. The origin_id, a Symbol, identifies the starting state for this transition. The state identified by origin_id will be created within the statemachine or superstate which this transition is declared. The event paramter should be a Symbol. The destination_id, which should also be a Symbol, is the id of the state that will event will transition into. This method will not create destination states within the current statemachine of superstate. If the state destination state should exist here, that declare with with the state method or declare a transition starting at the state.
sm = Statemachine.build do
trans :locked, :coin, :unlocked, :unlock
end
# File lib/statemachine/builder.rb, line 163
163: def trans(origin_id, event, destination_id, action = nil)
164: origin = acquire_state_in(origin_id, @subject)
165: origin.add(Transition.new(origin_id, destination_id, event, action))
166: end
