Class Scheduler.Worker

java.lang.Object

rx.Scheduler.Worker

All Implemented Interfaces:

Subscription

Enclosing class:

Scheduler

public abstract static class Scheduler.Worker
extends java.lang.Object
implements Subscription

Sequential Scheduler for executing actions on a single thread or event loop.

Unsubscribing the Scheduler.Worker cancels all outstanding work and allows resources cleanup.

Method Detail

schedule

public abstract Subscription schedule(Action0 action)

Schedules an Action for execution.

Parameters:

action - Action to schedule

Returns:

a subscription to be able to prevent or cancel the execution of the action

schedule

public abstract Subscription schedule(Action0 action,
                                      long delayTime,
                                      java.util.concurrent.TimeUnit unit)

Schedules an Action for execution at some point in the future.

Note to implementors: non-positive delayTime should be regarded as non-delayed schedule, i.e., as if the schedule(rx.functions.Action0) was called.

Parameters:

action - the Action to schedule

delayTime - time to wait before executing the action; non-positive values indicate an non-delayed schedule

unit - the time unit of delayTime

Returns:

a subscription to be able to prevent or cancel the execution of the action

schedulePeriodically

public Subscription schedulePeriodically(Action0 action,
                                         long initialDelay,
                                         long period,
                                         java.util.concurrent.TimeUnit unit)

Schedules a cancelable action to be executed periodically. This default implementation schedules recursively and waits for actions to complete (instead of potentially executing long-running actions concurrently). Each scheduler that can do periodic scheduling in a better way should override this.

Note to implementors: non-positive initialTime and period should be regarded as non-delayed scheduling of the first and any subsequent executions.

Parameters:

action - the Action to execute periodically

initialDelay - time to wait before executing the action for the first time; non-positive values indicate an non-delayed schedule

period - the time interval to wait each time in between executing the action; non-positive values indicate no delay between repeated schedules

unit - the time unit of period

Returns:

a subscription to be able to prevent or cancel the execution of the action

now

public long now()

Gets the current time, in milliseconds, according to this Scheduler.

Returns:

the scheduler's notion of current absolute time in milliseconds
