Constructor Detail

PublishingCacheStore

public PublishingCacheStore(String cacheName)

Standard Constructor

Parameters:

cacheName - The name of the cache from which CacheEvents will be distributed.

Method Detail

isDistributable

protected boolean isDistributable(Event event,
                      EventDistributor distributor,
                      EventDistributorTemplate template)

Determine if an Event should be distributed by an EventDistributor.

Parameters:

event - the Event

distributor - the EventDistributor that would distribute the Event

template - the EventDistributorTemplate for the EventDistributor

Returns:

true if the Event should be sent to the EventDistributor

distribute

protected void distribute(Event event)

Requests an Event to be distributed via the established EventDistributors.

Parameters:

event - The Event to distribute.

distribute

protected void distribute(List<Event> events)

Requests a collection of Events to be distributed via the established EventDistributors.

Parameters:

events - The List of Events to distribute.

loadAll

public void loadAll(Set setBinEntries)

Specified by:

loadAll in interface com.tangosol.net.cache.BinaryEntryStore

store

public void store(com.tangosol.util.BinaryEntry entry)

The store method requests than an entry be distributed using the configured EventDistributorBuilder. The method checks to see that the entry wasn't marked for removal (removes are not distributed here, they're distributed on erase). It will then decorates the BinaryEntry with the affilitate associated and requests that the EventDistributorBuilder distribute the event.

Specified by:

store in interface com.tangosol.net.cache.BinaryEntryStore

Parameters:

entry - The BinaryEntry that was stored

erase

public void erase(com.tangosol.util.BinaryEntry entry)

The erase method distributes an EntryRemovedEvent with the EventDistributor.

Specified by:

erase in interface com.tangosol.net.cache.BinaryEntryStore

Parameters:

entry - The entry that was erased

storeAll

public void storeAll(Set colEntries)

The storeAll method distributes a batch of events with the EventDistributor. The method ensures that each entry wasn't marked for delete (delete events are not distributed here, they're distributed on erase). It will then decorate the BinaryEntry with the ClusterMetaInfo and request that the EventDistributor distributed the operation.

Specified by:

storeAll in interface com.tangosol.net.cache.BinaryEntryStore

Parameters:

colEntries - the collection of Entries that were stored

eraseAll

public void eraseAll(Set setEntries)

The eraseAll method will distribute a collection of erased entries using the EventDistributor.

Specified by:

eraseAll in interface com.tangosol.net.cache.BinaryEntryStore

Parameters:

setEntries - The entries that were erased

load

public void load(com.tangosol.util.BinaryEntry binaryEntry)

Specified by:

load in interface com.tangosol.net.cache.BinaryEntryStore

getExpiry

protected long getExpiry(com.tangosol.util.BinaryEntry entry)

Obtains the time the specified BinaryEntry will expire, relative to the epoc, not a delta time.

Parameters:

entry - the BinaryEntry

Returns:

the expiry time
