trait ReferenceScheduler extends Scheduler
Helper for building a Scheduler.
You can inherit from this class and provided a correct scheduleOnce you'll get Scheduler.scheduleWithFixedDelay and Scheduler.scheduleAtFixedRate for free.

executionModel: execution.ExecutionModel
The ExecutionModel is a specification of how run-loops and producers should behave in regards to executing tasks either synchronously or asynchronously.

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.

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 useSystem.currentTimeMillis()
directly, prefer this method instead, because then it can be mocked for testing purposes (see for example TestScheduler)- Definition Classes

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
theninitialDelay + period
, theninitialDelay + 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 theperiod
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.

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

- delay

- unit

def
withExecutionModel(em: execution.ExecutionModel): Scheduler
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):
- the source
Scheduler
must not be modified in any way - 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)) }

Package Overview
monix.execution exposes lower level primitives for dealing with asynchronous execution:
Atomic
types, as alternative tojava.util.concurrent.atomic
monix.eval is for dealing with evaluation of results, thus exposing Task and Coeval.
monix.reactive exposes the
Observable
pattern:Observable
implementationsmonix.types implements type-class shims, to be translated to type-classes provided by libraries such as Cats or Scalaz.
monix.cats is the optional integration with the Cats library, providing translations for the types described in
monix.types
.monix.scalaz is the optional integration with the Scalaz library, providing translations for the types described in
monix.types
.
