    Schedule the Runnable on the TickWheelExecutor

    Schedule the Runnable on the TickWheelExecutor

    timeouts of Inf duration are ignored, timeouts of zero or negative duration are executed immediately on the submitting thread.

    r

    Runnable to be executed

    ec

    ExecutionContext to submit the Runnable

    timeout

    Duration to wait before execution

    returns

    a Cancellable. This is not a java.util.concurrent.Cancellable, which is a richer interface.

    Schedule the Runnable on the TickWheelExecutor

    Schedule the Runnable on the TickWheelExecutor

    Execution is performed on the TickWheelExecutors thread, so only extremely small tasks should be submitted with this method. timeouts of Inf duration are ignored, timeouts of zero or negative duration are executed immediately on the submitting thread.

    r

    Runnable to be executed

    timeout

    Duration to wait before execution

    returns

    a Cancellable. This is not a java.util.concurrent.Cancellable, which is a richer interface.
