Constructor Summary

DistributedCache()

Method Summary

void	batchUpdate(Map additions, Map updates, Collection deletes, Object origin) Overridden batchUpdate() method that invokes broadcastUpdate() after updating the cache.
protected abstract void	broadcastUpdate(Map additions, Map updates, Collection deletes) Notifys other PersistenceManagerFactory caches in this JVM and on other machines of changes to the cache.
protected void	log(String s) Log the message to the logging framework.
protected void	log(String s, Throwable t) Log the message to the logging framework.
protected void	receivedBatchUpdate(Collection additions, Collection updates, Collection deletes) Invoked when a notification of update has been received from a different cache, and that this cache should therefore be updated as appropriate.

Method Detail

batchUpdate

public void batchUpdate(Map additions,
                        Map updates,
                        Collection deletes,
                        Object origin)

Overridden batchUpdate() method that invokes broadcastUpdate() after updating the cache.

Overrides:

batchUpdate in class LocalCache

Following copied from interface: com.solarmetric.kodo.runtime.datacache.DataCache

Parameters:

origin - the object that initiated this cache update. This can be useful for implementations in which many sources share a single cache, which in turn communicates back to the sources on cache updates.

receivedBatchUpdate

protected void receivedBatchUpdate(Collection additions,
                                   Collection updates,
                                   Collection deletes)

Invoked when a notification of update has been received from a different cache, and that this cache should therefore be updated as appropriate. This implementation drops all the keys listed in additions, updates, and deletes.

broadcastUpdate

protected abstract void broadcastUpdate(Map additions,
                                        Map updates,
                                        Collection deletes)

Notifys other PersistenceManagerFactory caches in this JVM and on other machines of changes to the cache.

log

protected void log(String s)

Log the message to the logging framework.

log

protected void log(String s,
                   Throwable t)

Log the message to the logging framework.
