Field Detail

cacheMgr

protected static transient CompositeCacheManager cacheMgr

The hub, the cache manager, the master controller . . .

instance

protected static IRemoteCacheListener instance

Singleton instance of the listener

irca

Remote cache configuration attributes.

Constructor Detail

RemoteCacheServerListener

protected RemoteCacheServerListener(IRemoteCacheAttributes irca)

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

Exports this remote object to make it available to receive incoming calls, using an anonymous port if none is specified.

Parameters:

irca - the atttributes, the LocalPort specifies the receiving port.

Method Detail

setListenerId

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

Let the remote 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 IRemoteCacheListener

Parameters:

id - The new listenerId value

Throws:

java.io.IOException

getListenerId

public long getListenerId()
                   throws java.io.IOException

Gets the listenerId attribute of the RemoteCacheServerListener object

Specified by:

getListenerId in interface IRemoteCacheListener

Returns:

The listenerId value

Throws:

java.io.IOException

getRemoteType

public int getRemoteType()
                  throws java.io.IOException

Gets the remoteType attribute of the RemoteCacheServerListener object

Specified by:

getRemoteType in interface IRemoteCacheListener

Returns:

The remoteType value

Throws:

java.io.IOException

getInstance

public static IRemoteCacheListener getInstance(IRemoteCacheAttributes irca)

Gets the instance attribute of the RemoteCacheServerListener class

Parameters:

irca -

Returns:

The instance value

handlePut

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

Just remove the element since it has been updated elsewhere cd should be incomplete for faster transmission. We don't want to pass data only invalidation. The next time it is used the local cache will get the new version from the remote store

Specified by:

handlePut in interface ICacheListener

Parameters:

cb -

Throws:

java.io.IOException

handleRemove

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

Calls remove for the key on the named cache

Specified by:

handleRemove in interface ICacheListener

Parameters:

cacheName -

key -

Throws:

java.io.IOException

handleRemoveAll

public void handleRemoveAll(java.lang.String cacheName)
                     throws java.io.IOException

Calls removeAl on the named cache region.

Specified by:

handleRemoveAll in interface ICacheListener

Parameters:

cacheName -

Throws:

java.io.IOException

handleDispose

public void handleDispose(java.lang.String cacheName)
                   throws java.io.IOException

Calls freeCache on the named region.

Specified by:

handleDispose in interface ICacheListener

Parameters:

cacheName -

Throws:

java.io.IOException

getCacheManager

protected void getCacheManager()

Gets the cacheManager attribute of the RemoteCacheServerListener object
