Abstract Value Members

  1. abstract def stateChanged(service: Service): Unit

    Callback to notify of a state change.

    Callback to notify of a state change. The service will already have changed state before this callback is invoked.

    This operation is invoked on the thread that initiated the state change, while the service itself in a synchronized section.

    • Any long-lived operation here will prevent the service state change from completing in a timely manner.
    • If another thread is somehow invoked from the listener, and that thread invokes the methods of the service (including subclass-specific methods), there is a risk of a deadlock.
    service

    the service that has changed.
