Package com.jalios.jcms

Class JSyncDataListener

java.lang.Object

com.jalios.jcms.BasicStoreListener

com.jalios.jcms.JSyncDataListener

All Implemented Interfaces:

JcmsConstants, PluginComponent, AlarmListener, JSyncConstants, StoreListener, JaliosConstants

public class JSyncDataListener
extends BasicStoreListener
implements AlarmListener, JSyncConstants, JcmsConstants

This class monitors writes stablization. Once writes are stabilized (i.e. once there is no new write during a given time), it calls the update() method of the JSyncReplica. Nevertheless, if write rate is high, it forces update sending once the max delay has been reached.

JSyncDataListener

public JSyncDataListener(int maxDelay)

Method Detail

handleAlarm

public void handleAlarm(AlarmEntry entry)

Description copied from interface: AlarmListener

Invoked when an alarm is triggered.

Specified by:

handleAlarm in interface AlarmListener

Parameters:

entry - the AlarmEntry which has been triggered.

handleCreate

public void handleCreate(Storable storable,
                         boolean firstTime)

Description copied from interface: StoreListener

This method gets called when a storable is created.

Specified by:

handleCreate in interface StoreListener

Overrides:

handleCreate in class BasicStoreListener

Parameters:

storable - the storable

firstTime - true if it is the first time this operation is processed

See Also:

StoreListener.handleCreate(Storable, boolean)

handleCommitUpdate

public void handleCommitUpdate(Storable storable,
                               Storable oldStorable,
                               boolean firstTime)

Description copied from interface: StoreListener

This method gets called when after a storable has been updated.

Specified by:

handleCommitUpdate in interface StoreListener

Overrides:

handleCommitUpdate in class BasicStoreListener

Parameters:

storable - the storable, this instance is the object that was created at first and that will be stored in jcms until deletion of the storable with this ID. You should always manipulate this object if you maintain any index.

oldStorable - the previous version of the storable, it is a clone, do not use in any index, it should only be used to access old values.

firstTime - true if it is the first time this operation is processed

See Also:

StoreListener.handleCommitUpdate(Storable, Storable, boolean)

handleDelete

public void handleDelete(Storable storable,
                         boolean firstTime)

Description copied from interface: StoreListener

This method gets called when a storable is deleted.

Specified by:

handleDelete in interface StoreListener

Overrides:

handleDelete in class BasicStoreListener

Parameters:

storable - the storable

firstTime - true if it is the first time this operation is processed

See Also:

StoreListener.handleDelete(Storable, boolean)
