schedulePeriodicSampler

public final ScheduledSamplerJob schedulePeriodicSampler(ISampler sensor,
                                          long initialDelay,
                                          long period,
                                          java.util.concurrent.TimeUnit timeUnit)

Schedules the given ISampler with given initial delay, and period.

Specified by:

schedulePeriodicSampler in interface ISamplingController

Parameters:

sensor - The sampler to schedule.

initialDelay - The initial delay.

period - The period.

timeUnit - The time unit which determines how to interpret the given parameter.

Returns:

a ScheduledSamplerJob as a handler for removing the scheduled sampler later on by using the method ISamplingController.removeScheduledSampler(ScheduledSamplerJob).

removeScheduledSampler

public final boolean removeScheduledSampler(ScheduledSamplerJob sensorJob)

Stops future executions of the given periodic ScheduledSamplerJob .

Specified by:

removeScheduledSampler in interface ISamplingController

Parameters:

sensorJob - The sampler to be removed.

Returns:

true if the sensor is not registered
