Constructor Details

#initialize(state:, data:, name:, vertex: nil) ⇒ Full

param state: Symbol, one of StateMachine.GRAPH.vertices param data: all data returned by a Vertice’s Payload param name: Symboli -c name of the associated Vertex param vertex: Vertex that produced the data

def initialize state:, data:, name:, vertex: nil
  # observation: Ractor.current returns Vertex object if invoked from a Vertex
  super(name:, vertex: vertex || Ractor.current)
  @state = state
  @data = data
end

Dynamic Method Handling

This class handles dynamic methods through the method_missing method

#method_missing(method, *_args, &_block) ⇒ Object

auto-generated methods to check states easier; note: define_method causes these object to become un-shareable what breaks Broker’s messaging

Raises:

  • (NoMethodError)
