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 unsubscribe the action (unschedule it if not executed)

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.

Parameters:

action - the Action to schedule

delayTime - time to wait before executing the action

unit - the time unit the delay time is given in

Returns:

a subscription to be able to unsubscribe the action (unschedule it if not executed)

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.

Parameters:

action - the Action to execute periodically

initialDelay - time to wait before executing the action for the first time

period - the time interval to wait each time in between executing the action

unit - the time unit the interval above is given in

Returns:

a subscription to be able to unsubscribe the action (unschedule it if not executed)

now

public long now()

Returns:

the scheduler's notion of current absolute time in milliseconds.
