Abstract Value Members

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

    Extract the entry id from an incoming message.

    Extract the entry 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 entryMessage(message: Any): Any

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

    Extract the message to send to the entry 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 entry actor.

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

    Extract the entry id from an incoming message.

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