Package com.adaptris.core

Class GaussianIntervalPoller

java.lang.Object

com.adaptris.core.PollerImp

com.adaptris.core.ScheduledTaskPoller

com.adaptris.core.GaussianIntervalPoller

All Implemented Interfaces:

ComponentLifecycle, Poller

public class GaussianIntervalPoller
extends ScheduledTaskPoller

Implementation of Poller which polls at a random interval with a normal distribution.

Note: Logic is as follows:

Random.nextGaussian() * getMeanInterval() + getStandardDeviationInterval().

In the adapter configuration file this class is aliased as gaussian-interval-poller which is the preferred alternative to the fully qualified classname when building your configuration.

Constructor Detail

GaussianIntervalPoller

public GaussianIntervalPoller()

Creates a new instance. Default mean is 0 seconds and standard deviation is 20 seconds.

GaussianIntervalPoller

public GaussianIntervalPoller(TimeInterval meanInterval,
                              TimeInterval standardDeviationInterval)

Method Detail

init

public void init()
          throws CoreException

Description copied from interface: ComponentLifecycle

Initialises the component.

Component initialisation includes config verification, creation of connections etc.

Specified by:

init in interface ComponentLifecycle

Overrides:

init in class ScheduledTaskPoller

Throws:

CoreException - wrapping any underlying Exceptions

scheduleTask

protected void scheduleTask()

Specified by:

scheduleTask in class ScheduledTaskPoller

getMeanInterval

public TimeInterval getMeanInterval()

setMeanInterval

public void setMeanInterval(TimeInterval meanInterval)

Set the mean to be used in poll interval calculation.

Parameters:

meanInterval - the mean interval (default 0 seconds)

getStandardDeviationInterval

public TimeInterval getStandardDeviationInterval()

setStandardDeviationInterval

public void setStandardDeviationInterval(TimeInterval standardDeviationInterval)

Set the standard deviation to be used in poll interval calculation.

Parameters:

standardDeviationInterval - the standard deviation interval (default 20 seconds)
