  6. def currentTimeMillis(): Long

    Returns the current time in milliseconds.

    Returns the current time in milliseconds. Note that while the unit of time of the return value is a millisecond, the granularity of the value depends on the underlying operating system and may be larger. For example, many operating systems measure time in units of tens of milliseconds.

    It's the equivalent of System.currentTimeMillis(). When wanting to measure time, do not use System.currentTimeMillis() directly, prefer this method instead, because then it can be mocked for testing purposes (see for example TestScheduler)

  9. final def execute(runnable: Runnable): Unit

    Schedules the given command for execution at some time in the future.

    The command may execute in a new thread, in a pooled thread, in the calling thread, basically at the discretion of the Scheduler implementation.

  20. def scheduleAtFixedRate(initialDelay: Long, period: Long, unit: TimeUnit, r: Runnable): Cancelable

    Schedules a periodic task that becomes enabled first after the given initial delay, and subsequently with the given period.

    Schedules a periodic task that becomes enabled first after the given initial delay, and subsequently with the given period. Executions will commence after initialDelay then initialDelay + period, then initialDelay + 2 * period and so on.

    If any execution of the task encounters an exception, subsequent executions are suppressed. Otherwise, the task will only terminate via cancellation or termination of the scheduler. If any execution of this task takes longer than its period, then subsequent executions may start late, but will not concurrently execute.

    For example the following schedules a message to be printed to standard output approximately every 10 seconds with an initial delay of 5 seconds:

    val task = scheduler.scheduleAtFixedRate(5, 10, TimeUnit.SECONDS, new Runnable {
      def run() = print("Repeated message")
    })
    
    // later if you change your mind ...
    task.cancel()
    initialDelay

    is the time to wait until the first execution happens

    period

    is the time to wait between 2 successive executions of the task

    unit

    is the time unit used for the initialDelay and the period parameters

    r

    is the callback to be executed

    returns

    a cancelable that can be used to cancel the execution of this repeated task at any time.

  21. def scheduleOnce(initialDelay: Long, unit: TimeUnit, r: Runnable): Cancelable

    Schedules a task to run in the future, after initialDelay.

    Schedules a task to run in the future, after initialDelay.

    For example the following schedules a message to be printed to standard output after 5 minutes:

    val task = scheduler.scheduleOnce(5, TimeUnit.MINUTES, new Runnable {
      def run() = print("Hello, world!")
    })
    
    // later if you change your mind ...
    task.cancel()
    initialDelay

    is the time to wait until the execution happens

    unit

    is the time unit used for initialDelay

    r

    is the callback to be executed

    returns

    a Cancelable that can be used to cancel the created task before execution.

  22. def scheduleWithFixedDelay(initialDelay: Long, delay: Long, unit: TimeUnit, r: Runnable): Cancelable

    Schedules for execution a periodic task that is first executed after the given initial delay and subsequently with the given delay between the termination of one execution and the commencement of the next.

    Schedules for execution a periodic task that is first executed after the given initial delay and subsequently with the given delay between the termination of one execution and the commencement of the next.

    For example the following schedules a message to be printed to standard output every 10 seconds with an initial delay of 5 seconds:

    val task = s.scheduleWithFixedDelay(5, 10, TimeUnit.SECONDS, new Runnable {
      def run() = print("Repeated message")
    })
    
    // later if you change your mind ...
    task.cancel()
    initialDelay

    is the time to wait until the first execution happens

    delay

    is the time to wait between 2 successive executions of the task

    unit

    is the time unit used for the initialDelay and the delay parameters

    r

    is the callback to be executed

    returns

    a cancelable that can be used to cancel the execution of this repeated task at any time.

  28. def withExecutionModel(em: execution.ExecutionModel): AsyncScheduler

    Given a function that will receive the underlying ExecutionModel, returns a new Scheduler reference, based on the source, that exposes the transformed ExecutionModel when queried by means of the executionModel property.

    Given a function that will receive the underlying ExecutionModel, returns a new Scheduler reference, based on the source, that exposes the transformed ExecutionModel when queried by means of the executionModel property.

    This method enables reusing global scheduler references in a local scope, but with a slightly modified execution model to inject.

    The contract of this method (things you can rely on):

    1. the source Scheduler must not be modified in any way
    2. the implementation should wrap the source efficiently, such that the result mirrors the source Scheduler in every way except for the execution model

    Sample:

    import monix.execution.Scheduler.global
    
    implicit val scheduler = {
      val em = global.executionModel
      global.withExecutionModel(em.withAutoCancelableLoops(true))
    }
