- ## Method Details

  - ### execute

    void execute()
    Called when the messaging connection allowing the server to send messages to the client is disconnected. This can occur either when you explicitly disconnect the connection or if a keepalive packet from the server does not arrive on time. This latter is defined as the `messaging.keepaliveInterval` plus the `messaging.keepaliveReestablishDelay`. With default settings, a maximum of 4 seconds will elapse between the connection actually going down and you receiving this callback.
