Scheduler

trait Scheduler extends AnyRef

An object that schedules isolates for execution.

After an isolate is instantiated, its isolate frame is assigned a scheduler by the isolate system. An isolate that is assigned a specific scheduler will always be executed on that same scheduler.

After creating an isolate, every isolate system will first call the initiate method on the isolate frame. Then, the isolate system will call the schedule method every time there are events ready for the isolate.

Note: Clients never invoke Scheduler operations directly, but can implement their own scheduler if necessary.

Abstract Value Members

  1. abstract def handler: Handler

    The handler for the fatal errors that are not sent to the failures stream of the isolate.

    The handler for the fatal errors that are not sent to the failures stream of the isolate.

    Note: If the failures reactive throws while handling any throwables passed to it, then those throwables are passed to this error handler. This means that the handler can also receive non-fatal errors.

  2. abstract def initiate[T](frame: IsolateFrame[T]): Unit

    Initiates the isolate frame.

    Initiates the isolate frame. Clients never call this method directly.

    The scheduler can use the schedulerInfo field of the isolate frame to store its custom configuration objects for this isolate frame. For example, a Scheduler based on a Java Executor would typically store a Runnable object here and later use it from the schedule method.

    frame

    the isolate frame to initiate

  3. abstract def schedule[T](frame: IsolateFrame[T]): Unit

    Schedules an isolate frame for execution.

    Schedules an isolate frame for execution. Clients never call this method directly.

    This method uses the isolate frame to flush messages from its event queue and propagate events through the isolate.

    frame

    the isolate frame to schedule
