Abstract Value Members

  1. abstract def entityId(message: Any): String

    Extract the entity id from an incoming message.

    Extract the entity id from an incoming message. If null is returned the message will be unhandled, i.e. posted as Unhandled messages on the event stream

  2. abstract def entityMessage(message: Any): Any

    Extract the message to send to the entity from an incoming message.

    Extract the message to send to the entity from an incoming message. Note that the extracted message does not have to be the same as the incoming message to support wrapping in message envelope that is unwrapped before sending to the entity actor.

  3. abstract def shardId(message: Any): String

    Extract the shard id from an incoming message.

    Extract the shard id from an incoming message. Only messages that passed the #entityId function will be used as input to this function.

    Deprecated

    (Since version 2.12.16) Use formatString.format(value) instead of value.formatted(formatString), or use the f"" string interpolator. In Java 15 and later, formatted resolves to the new method in String which has reversed parameters.

    (Since version 2.13.0) Use -> instead. If you still wish to display it as one character, consider using a font with programming ligatures such as Fira Code.
