notifyElementUpdated

public final void notifyElementUpdated(Unity element)

Notifies all registered listeners, in no guaranteed order, that an element in the cache was updated

参数:

element -

remoteEvent - whether the event came from a remote cache peer

notifyElementExpiry

public final void notifyElementExpiry(Unity element)

Notifies all registered listeners, in no guaranteed order, that an element has expired

参数:

element - the Element to perform the notification on

remoteEvent - whether the event came from a remote cache peer

CacheEventListener.notifyElementExpired(com.fr.cache.FRCache, com.fr.cache.Unity)

hasCacheEventListeners

public final boolean hasCacheEventListeners()

Returns whether or not at least one cache event listeners has been registered.

返回:

true if a one or more listeners have registered, otherwise false

notifyElementEvicted

public void notifyElementEvicted(Unity element)

Notifies all registered listeners, in no guaranteed order, that an element has been evicted from the cache

参数:

element - the Element to perform the notification on

remoteEvent - whether the event came from a remote cache peer

另请参阅:

CacheEventListener.notifyElementEvicted(com.fr.cache.FRCache, com.fr.cache.Unity)

notifyRemoveAll

public void notifyRemoveAll(boolean remoteEvent)

Notifies all registered listeners, in no guaranteed order, that removeAll has been called and all elements cleared

参数:

remoteEvent - whether the event came from a remote cache peer

另请参阅:

CacheEventListener.notifyElementEvicted(com.fr.cache.FRCache, com.fr.cache.Unity)

registerListener

public final boolean registerListener(CacheEventListener cacheEventListener)

Adds a listener to the notification service. No guarantee is made that listeners will be notified in the order they were added.

参数:

cacheEventListener -

返回:

true if the listener is being added and was not already added

unregisterListener

public final boolean unregisterListener(CacheEventListener cacheEventListener)

Removes a listener from the notification service.

参数:

cacheEventListener -

返回:

true if the listener was present

getCacheEventListeners

public final java.util.Set getCacheEventListeners()

Gets a list of the listeners registered to this class

返回:

a list of type CacheEventListener

dispose

public final void dispose()

Tell listeners to dispose themselves. Because this method is only ever called from a synchronized cache method, it does not itself need to be synchronized.

toString

public final java.lang.String toString()

Returns a string representation of the object. In general, the toString method returns a string that "textually represents" this object. The result should be a concise but informative representation that is easy for a person to read.

返回:

a string representation of the object.
