Class LateralCacheJGListener

java.lang.Object
  org.apache.jcs.auxiliary.lateral.javagroups.LateralCacheJGListener

All Implemented Interfaces:

ICacheListener, ILateralCacheJGListener, ILateralCacheListener, java.io.Serializable

Direct Known Subclasses:

LateralGroupCacheJGListener

public class LateralCacheJGListener

extends java.lang.Object

implements ILateralCacheJGListener, java.io.Serializable

JavaGroups listener. Good for distributing cache data accross multiple vms on the same machine. You also don't need to know the number of listerners for configuration.

Constructor Detail

LateralCacheJGListener

protected LateralCacheJGListener(ILateralCacheAttributes ilca)

Only need one since it does work for all regions, just reference by multiple region names.

Parameters:

ilca -

Method Detail

init

public void init()

Description of the Method

Specified by:

init in interface ILateralCacheJGListener

setListenerId

public void setListenerId(long id)
                   throws java.io.IOException

let the lateral cache set a listener_id. Since there is only one listerenr for all the regions and every region gets registered? the id shouldn't be set if it isn't zero. If it is we assume that it is a reconnect.

Specified by:

setListenerId in interface ICacheListener

Parameters:

id - The new listenerId value

Throws:

java.io.IOException

getListenerId

public long getListenerId()
                   throws java.io.IOException

Gets the listenerId attribute of the LateralCacheJGListener object

Specified by:

getListenerId in interface ICacheListener

Returns:

The listenerId value

Throws:

java.io.IOException

getInstance

public static ILateralCacheListener getInstance(ILateralCacheAttributes ilca)

Gets the instance attribute of the LateralCacheJGListener class

Parameters:

ilca -

Returns:

The instance value

handlePut

public void handlePut(ICacheElement element)
               throws java.io.IOException

Description copied from interface: ICacheListener

Notifies the subscribers for a cache entry update.

Specified by:

handlePut in interface ICacheListener

Throws:

java.io.IOException

handleRemove

public void handleRemove(java.lang.String cacheName,
                         java.io.Serializable key)

handleRemove in interface ICacheListener

Parameters:

cacheName -

key -

Throws:

Parameters:

cacheName -

Throws:

java.io.IOException

handleGet

public java.io.Serializable handleGet(java.lang.String cacheName,
                                      java.io.Serializable key)
                               throws java.io.IOException

Test get implementation.

Specified by:

handleGet in interface ILateralCacheJGListener

Parameters:
