trait FlagCloseable extends AutoCloseable

Provides a way to synchronize closing with other running tasks in the class, such that new tasks aren't scheduled while closing, and such that closing waits for the scheduled tasks.

The component's custom shutdown behaviour should override the onClosed method.

  20. def performUnlessClosing[A](f: => A)(implicit traceContext: TraceContext): UnlessShutdown[A]

    Performs the task given by f unless a shutdown has been initiated.

    Performs the task given by f unless a shutdown has been initiated. The shutdown will only begin after f completes, but other tasks may execute concurrently with f, if started using this function, or one of the other variants (performUnlessClosingF and performUnlessClosingEitherT). The tasks are assumed to take less than closingTimeout to complete.

    f

    The task to perform

    returns

    scala.None$ if a shutdown has been initiated. Otherwise the result of the task.

  21. def performUnlessClosingEitherT[E, R](onClosing: => E)(etf: => EitherT[Future, E, R])(implicit ec: ExecutionContext, traceContext: TraceContext): EitherT[Future, E, R]

    Performs the EitherT[Future] given by etf unless a shutdown has been initiated, in which case the provided error is returned instead.

    Performs the EitherT[Future] given by etf unless a shutdown has been initiated, in which case the provided error is returned instead. Both etf and the error are lazy; etf is only evaluated if there is no shutdown, the error only if we're shutting down. The shutdown will only begin after etf completes, but other tasks may execute concurrently with etf, if started using this function, or one of the other variants (performUnlessClosing and performUnlessClosingF). The tasks are assumed to take less than closingTimeout to complete.

    etf

    The task to perform

  22. def performUnlessClosingEitherTF[E, R](onClosing: => E)(etf: => EitherT[Future, E, Future[R]])(implicit ec: ExecutionContext, traceContext: TraceContext): EitherT[Future, E, Future[R]]
  23. def performUnlessClosingF[A](f: => Future[A])(implicit ec: ExecutionContext, traceContext: TraceContext): FutureUnlessShutdown[A]

    Performs the Future given by f unless a shutdown has been initiated.

    Performs the Future given by f unless a shutdown has been initiated. The future is lazy and not evaluated during shutdown. The shutdown will only begin after f completes, but other tasks may execute concurrently with f, if started using this function, or one of the other variants (performUnlessClosing and performUnlessClosingEitherT). The tasks are assumed to take less than closingTimeout to complete.

    f

    The task to perform

    returns

    The future completes with com.digitalasset.canton.lifecycle.UnlessShutdown.AbortedDueToShutdown if a shutdown has been initiated. Otherwise the result of the task wrapped in com.digitalasset.canton.lifecycle.UnlessShutdown.Outcome.

  24. def runOnShutdown[T](task: RunOnShutdown)(implicit traceContext: TraceContext): Unit

    Register a task that will run onClose after all "performUnlessShutdown" tasks have finished
