public Class TerracottaCacheEventReplication

Overrides java.lang.Object.clone.

Implements net.sf.ehcache.event.CacheEventListener.clone.

Doc from net.sf.ehcache.event.CacheEventListener.clone.

Creates a clone of this listener. This method will only be called by ehcache before a cache is initialized.

This may not be possible for listeners after they have been initialized. Implementations should throw CloneNotSupportedException if they do not support clone.

Returns:TerracottaCacheEventReplication

a clone

Annotations

@Override

Exceptions

CloneNotSupportedException:

if the listener could not be cloned.

Implements net.sf.ehcache.event.CacheEventListener.dispose.

Doc from net.sf.ehcache.event.CacheEventListener.dispose.

Give the listener a chance to cleanup and free resources when no longer needed

Implements net.sf.ehcache.event.CacheEventListener.notifyElementEvicted.

Doc from net.sf.ehcache.event.CacheEventListener.notifyElementEvicted.

Called immediately after an element is evicted from the cache. Evicted in this sense means evicted from one store and not moved to another, so that it exists nowhere in the local cache.

In a sense the Element has been removed from the cache, but it is different, thus the separate notification.

Parameters

cache:Ehcache

the cache emitting the notification

element:Element

the element that has just been evicted

Implements net.sf.ehcache.event.CacheEventListener.notifyElementExpired.

Doc from net.sf.ehcache.event.CacheEventListener.notifyElementExpired.

Called immediately after an element is found to be expired. The net.sf.ehcache.Cache#remove(Object) method will block until this method returns.

Elements are checked for expiry in ehcache at the following times:

• When a get request is made
• When an element is spooled to the diskStore in accordance with a MemoryStore eviction policy
• In the DiskStore when the expiry thread runs, which by default is net.sf.ehcache.Cache#DEFAULT_EXPIRY_THREAD_INTERVAL_SECONDS

Parameters

cache:Ehcache

the cache emitting the notification

element:Element

the element that has just expired

Deadlock Warning: expiry will often come from the DiskStore expiry thread. It holds a lock to the DiskStorea the time the notification is sent. If the implementation of this method calls into a synchronized Cache method and that subsequently calls into DiskStore a deadlock will result. Accordingly implementers of this method should not call back into Cache.

Implements net.sf.ehcache.event.CacheEventListener.notifyElementPut.

Doc from net.sf.ehcache.event.CacheEventListener.notifyElementPut.

Called immediately after an element has been put into the cache. The net.sf.ehcache.Cache#put(net.sf.ehcache.Element) method will block until this method returns.

Implementers may wish to have access to the Element's fields, including value, so the element is provided. Implementers should be careful not to modify the element. The effect of any modifications is undefined.

Parameters

cache:Ehcache

the cache emitting the notification

element:Element

the element which was just put into the cache.

Implements net.sf.ehcache.event.CacheEventListener.notifyElementRemoved.

Doc from net.sf.ehcache.event.CacheEventListener.notifyElementRemoved.

Called immediately after an attempt to remove an element. The remove method will block until this method returns.

This notification is received regardless of whether the cache had an element matching the removal key or not. If an element was removed, the element is passed to this method, otherwise a synthetic element, with only the key set is passed in.

This notification is not called for the following special cases:

1. removeAll was called. See notifyRemoveAll(net.sf.ehcache.Ehcache)
2. An element was evicted from the cache. See notifyElementEvicted(net.sf.ehcache.Ehcache, net.sf.ehcache.Element)

Parameters

cache:Ehcache

the cache emitting the notification

element:Element

the element just deleted, or a synthetic element with just the key set if no element was removed.

Implements net.sf.ehcache.event.CacheEventListener.notifyElementUpdated.

Doc from net.sf.ehcache.event.CacheEventListener.notifyElementUpdated.

Called immediately after an element has been put into the cache and the element already existed in the cache. This is thus an update.

The net.sf.ehcache.Cache#put(net.sf.ehcache.Element) method will block until this method returns.

Implementers may wish to have access to the Element's fields, including value, so the element is provided. Implementers should be careful not to modify the element. The effect of any modifications is undefined.

Parameters

cache:Ehcache

the cache emitting the notification

element:Element

the element which was just put into the cache.

Implements net.sf.ehcache.event.CacheEventListener.notifyRemoveAll.

Doc from net.sf.ehcache.event.CacheEventListener.notifyRemoveAll.

Called during net.sf.ehcache.Ehcache#removeAll() to indicate that the all elements have been removed from the cache in a bulk operation. The usual notifyElementRemoved(net.sf.ehcache.Ehcache, net.sf.ehcache.Element) is not called.

This notification exists because clearing a cache is a special case. It is often not practical to serially process notifications where potentially millions of elements have been bulk deleted.

Parameters

cache:Ehcache

the cache emitting the notification
