Enum EventType

  • All Implemented Interfaces:
    Serializable, Comparable<EventType>

    public enum EventType
    extends Enum<EventType>
    Due to the duality of some types (which can be states and commands at the same time), we need to be able to differentiate what the meaning of a message on the bus is - does "item ON" mean that its state has changed to ON or that it should turn itself ON? To decide this, we send the event type as an additional information on the event bus for each message.

      • values

        public static EventType[] values()
        Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:
        for (EventType c : EventType.values())
            System.out.println(c);
        
        Returns:
        an array containing the constants of this enum type, in the order they are declared
      • valueOf

        public static EventType valueOf​(String name)
        Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)
        Parameters:
        name - the name of the enum constant to be returned.
        Returns:
        the enum constant with the specified name
        Throws:
        IllegalArgumentException - if this enum type has no constant with the specified name
        NullPointerException - if the argument is null
