Class AbstractDelegatingCache<K,V>

java.lang.Object
  org.infinispan.AbstractDelegatingCache<K,V>

All Implemented Interfaces:

ConcurrentMap<K,V>, Map<K,V>, Cache<K,V>, Lifecycle, Listenable

Direct Known Subclasses:

AbstractDelegatingAdvancedCache

public abstract class AbstractDelegatingCache<K,V>
extends Object
implements Cache<K,V>

This is a convenient base class for implementing a cache delegate. The only constructor takes a Cache argument, to which each method call is delegated. One can extend this class and override the method sub-set it is interested in. There is also an similar implementation for AdvancedCache: AbstractDelegatingAdvancedCache.

putForExternalRead

public void putForExternalRead(K key,
                               V value)

Description copied from interface: Cache

Under special operating behavior, associates the value with the specified key.

• Only goes through if the key specified does not exist; no-op otherwise (similar to ConcurrentMap.putIfAbsent(Object, Object))
• Force asynchronous mode for replication to prevent any blocking.
• invalidation does not take place.
• 0ms lock timeout to prevent any blocking here either. If the lock is not acquired, this method is a no-op, and swallows the timeout exception.
• Ongoing transactions are suspended before this call, so failures here will not affect any ongoing transactions.
• Errors and exceptions are 'silent' - logged at a much lower level than normal, and this method does not throw exceptions

This method is for caching data that has an external representation in storage, where, concurrent modification and transactions are not a consideration, and failure to put the data in the cache should be treated as a 'suboptimal outcome' rather than a 'failing outcome'.

An example of when this method is useful is when data is read from, for example, a legacy datastore, and is cached before returning the data to the caller. Subsequent calls would prefer to get the data from the cache and if the data doesn't exist in the cache, fetch again from the legacy datastore.

See JBCACHE-848 for details around this feature.

Specified by:

putForExternalRead in interface Cache<K,V>

Parameters:

key - key with which the specified value is to be associated.

value - value to be associated with the specified key.

evict

public void evict(K key)

Description copied from interface: Cache

Evicts an entry from the memory of the cache. Note that the entry is not removed from any configured cache stores or any other caches in the cluster (if used in a clustered mode). Use Map.remove(Object) to remove an entry from the entire cache system.

This method is designed to evict an entry from memory to free up memory used by the application. This method uses a 0 lock acquisition timeout so it does not block in attempting to acquire locks. It behaves as a no-op if the lock on the entry cannot be acquired immediately.

Important: this method should not be called from within a transaction scope.

Specified by:

evict in interface Cache<K,V>

Parameters:

key - key to evict

getConfiguration

public Configuration getConfiguration()

Specified by:

getConfiguration in interface Cache<K,V>

startBatch

Returns:

true if a batch was successfully started; false if one was available and already running.

endBatch

public void endBatch(boolean successful)

Description copied from interface: Cache

Completes a batch if one has been started using Cache.startBatch(). If no batch has been started, this is a no-op.

Specified by:

endBatch in interface Cache<K,V>

Parameters:

successful - if true, the batch completes, otherwise the batch is aborted and changes are not committed.

Specified by:

compact

public void compact()

Description copied from interface: Cache

Method that releases object references of cached objects held in the cache by serializing them to byte buffers. Cached objects are lazily de-serialized when accessed again, based on the calling thread's context class loader.

This can be expensive, based on the effort required to serialize cached objects.

Specified by:

compact in interface Cache<K,V>

keySet

public Set<K> keySet()

Description copied from interface: Cache

Returns a set view of the keys contained in this cache. This set is immutable, so it cannot be modified and changes to the cache won't be reflected in the set. When this method is called on a cache configured with distribution mode, the set returned only contains the keys locally available in the cache instance. To avoid memory issues, there will be not attempt to bring keys from other nodes.

This method should only be used for debugging purposes such as to verify that the cache contains all the keys entered. Any other use involving execution of this method on a production system is not recommended.

Specified by:

keySet in interface Map<K,V>

Specified by:

keySet in interface Cache<K,V>

Returns:

a set view of the keys contained in this cache.

entrySet

public Set<Map.Entry<K,V>> entrySet()

Description copied from interface: Cache

Returns a set view of the mappings contained in this cache. This set is immutable, so it cannot be modified and changes to the cache won't be reflected in the set. Besides, each element in the returned set is an immutable Map.Entry. When this method is called on a cache configured with distribution mode, the set returned only contains the mappings locally available in the cache instance. To avoid memory issues, there will be not attempt to bring mappings from other nodes.

This method should only be used for debugging purposes such as to verify that the cache contains all the mappings entered. Any other use involving execution of this method on a production system is not recommended.

Specified by:

entrySet in interface Map<K,V>

Specified by:

entrySet in interface Cache<K,V>

Returns:

a set view of the mappings contained in this cache.

values

public Collection<V> values()

Description copied from interface: Cache

Returns a collection view of the values contained in this cache. This collection is immutable, so it cannot be modified and changes to the cache won't be reflected in the set. When this method is called on a cache configured with distribution mode, the collection returned only contains the values locally available in the cache instance. To avoid memory issues, there is not attempt to bring values from other nodes.

This method should only be used for testing or debugging purposes such as to verify that the cache contains all the values entered. Any other use involving execution of this method on a production system is not recommended.

Specified by:

values in interface Map<K,V>

Specified by:

values in interface Cache<K,V>

Returns:

a collection view of the values contained in this map.

stop

public void stop()

Specified by:

addListener

public void addListener(Object listener)

Description copied from interface: Listenable

Adds a listener to the component. Typically, listeners would need to be annotated with Listener and further to that, contain methods annotated appropriately, otherwise the listener will not be registered.

See the Listener annotation for more information.

Specified by:

addListener in interface Listenable

Parameters:

listener - must not be null.

removeListener

public void removeListener(Object listener)

Description copied from interface: Listenable

Removes a listener from the component.

Specified by:

removeListener in interface Listenable

Parameters:

listener - listener to remove. Must not be null.

getListeners

public Set<Object> getListeners()

Specified by:

getListeners in interface Listenable

Returns:

a set of all listeners registered on this component.

getAsync

public NotifyingFuture<V> getAsync(K key)

Description copied from interface: Cache

Asynchronous version of Map.get(Object) that allows user code to retrieve the value associated with a key at a later stage, hence allowing multiple parallel get requests to be sent. Normally, when this method detects that the value is likely to be retrieved from from a remote entity, it will span a different thread in order to allow the asynchronous get call to return immediately. If the call will definitely resolve locally, for example when the cache is configured with LOCAL mode and no cache loaders are configured, the get asynchronous call will act sequentially and will have no different to Map.get(Object).

Specified by:

getAsync in interface Cache<K,V>

Parameters:

key - key to retrieve

Returns:

a future that can be used to retrieve value associated with the key when this is available. The actual value returned by the future follows the same rules as Map.get(Object)

toString

public String toString()

Overrides:

toString in class Object
