Method Detail

withFlags

AdvancedCache<K,V> withFlags(Flag... flags)

A method that adds flags to any API call. For example, consider the following code snippet:

   cache.withFlags(Flag.FORCE_WRITE_LOCK).get(key);
 

will invoke a cache.get() with a write lock forced.

Note that for the flag to take effect, the cache operation must be invoked on the instance returned by this method.

As an alternative to setting this on every invocation, users should also consider saving the decorated cache, as this allows for more readable code. E.g.:

    AdvancedCache<?, ?> forceWriteLockCache = cache.withFlags(Flag.FORCE_WRITE_LOCK);
    forceWriteLockCache.get(key1);
    forceWriteLockCache.get(key2);
    forceWriteLockCache.get(key3);
 

Parameters:

flags - a set of flags to apply. See the Flag documentation.

Returns:

an AdvancedCache instance on which a real operation is to be invoked, if the flags are to be applied.

The outermost transformed cache.

withSubject

AdvancedCache<K,V> withSubject(Subject subject)

AuthorizationManager getAuthorizationManager()

Retrieves the AuthorizationManager if the cache has security enabled. Otherwise returns null

Returns:

an AuthorizationManager or null

lockAs

AdvancedCache<K,V> lockAs(Object lockOwner)

Whenever this cache acquires a lock it will do so using the given Object as the owner of said lock.

This can be useful when a lock may have been manually acquired and you wish to reuse that lock across invocations.

Great care should be taken with this command as misuse can very easily lead to deadlocks.

Parameters:

lockOwner - the lock owner to lock any keys as

Returns:

an AdvancedCache instance on which when an operation is invoked it will use lock owner object to acquire any locks

lock

boolean lock(K... keys)

Locks a given key or keys eagerly across cache nodes in a cluster.

Keys can be locked eagerly in the context of a transaction only.

Parameters:

keys - the keys to lock

Returns:

true if the lock acquisition attempt was successful for all keys; false will only be returned if the lock acquisition timed out and the operation has been called with Flag.FAIL_SILENTLY.

Throws:

TimeoutException - if the lock cannot be acquired within the configured lock acquisition time.

lock

boolean lock(Collection<? extends K> keys)

Locks collections of keys eagerly across cache nodes in a cluster.

Collections of keys can be locked eagerly in the context of a transaction only.

Parameters:

keys - collection of keys to lock

Returns:

true if the lock acquisition attempt was successful for all keys; false will only be returned if the lock acquisition timed out and the operation has been called with Flag.FAIL_SILENTLY.

Returns:

the data container associated with this cache instance

getLockManager

LockManager getLockManager()

Returns the component that deals with all aspects of acquiring and releasing locks for cache entries.

Returns:

retrieves the lock manager associated with this cache instance

getAll

Map<K,V> getAll(Set<?> keys)

Gets a collection of entries, returning them as Map of the values associated with the set of keys requested.

If the cache is configured read-through, and a get for a key would return null because an entry is missing from the cache, the Cache's CacheLoader is called in an attempt to load the entry. If an entry cannot be loaded for a given key, the returned Map will contain null for value of the key.

Unlike other bulk methods if this invoked in an existing transaction all entries will be stored in the current transactional context

The returned Map will be a copy and updates to the map will not be reflected in the Cache and vice versa. The keys and values themselves however may not be copies depending on if storeAsBinary is enabled and the value was retrieved from the local node.

Parameters:

keys - The keys whose associated values are to be returned.

Returns:

A map of entries that were found for the given keys. If an entry is not found for a given key, it will not be in the returned map.

Throws:

NullPointerException - if keys is null or if keys contains a null

getCacheEntry

CacheEntry<K,V> getCacheEntry(Object key)

Retrieves a CacheEntry corresponding to a specific key.

Parameters:

key - the key whose associated cache entry is to be returned

Returns:

the cache entry to which the specified key is mapped, or null if this map contains no mapping for the key

Since:

5.3

getCacheEntryAsync

default CompletableFuture<CacheEntry<K,V>> getCacheEntryAsync(Object key)

Retrieves a CacheEntry corresponding to a specific key.

Parameters:

key - the key whose associated cache entry is to be returned

Returns:

a future with the cache entry to which the specified key is mapped, or with null if this map contains no mapping for the key

Since:

9.2

getAllCacheEntries

Map<K,CacheEntry<K,V>> getAllCacheEntries(Set<?> keys)

Gets a collection of entries from the AdvancedCache, returning them as Map of the cache entries associated with the set of keys requested.

If the cache is configured read-through, and a get for a key would return null because an entry is missing from the cache, the Cache's CacheLoader is called in an attempt to load the entry. If an entry cannot be loaded for a given key, the returned Map will contain null for value of the key.

Unlike other bulk methods if this invoked in an existing transaction all entries will be stored in the current transactional context

The returned Map will be a copy and updates to the map will not be reflected in the Cache and vice versa. The keys and values themselves however may not be copies depending on if storeAsBinary is enabled and the value was retrieved from the local node.

Parameters:

keys - The keys whose associated values are to be returned.

Returns:

A map of entries that were found for the given keys. Keys not found in the cache are present in the map with null values.

Throws:

NullPointerException - if keys is null or if keys contains a null

getAndPutAll

default Map<K,V> getAndPutAll(Map<? extends K,? extends V> map)

Executes an equivalent of Map.putAll(Map), returning previous values of the modified entries.

Parameters:

map - mappings to be stored in this map

Returns:

A map of previous values for the given keys. If the previous mapping does not exist it will not be in the returned map.

Since:

9.1

getGroup

Map<K,V> getGroup(String groupName)

It fetches all the keys which belong to the group.

Semantically, it iterates over all the keys in memory and persistence, and performs a read operation in the keys found. Multiple invocations inside a transaction ensures that all the keys previous read are returned and it may return newly added keys to the group from other committed transactions (also known as phantom reads).

The map returned is immutable and represents the group at the time of the invocation. If you want to add or remove keys from a group use BasicCache.put(Object, Object) and BasicCache.remove(Object). To remove all the keys in the group use removeGroup(String).

To improve performance you may use the flag Flag.SKIP_CACHE_LOAD to avoid fetching the key/value from persistence. However, you will get an inconsistent snapshot of the group.

Parameters:

groupName - the group name.

Returns:

an immutable Map with the key/value pairs.

removeGroup

void removeGroup(String groupName)

It removes all the key which belongs to a group.

Semantically, it fetches the most recent group keys/values and removes them.

Note that, concurrent addition perform by other transactions/threads to the group may not be removed.

Parameters:

groupName - the group name.

getAvailability

AvailabilityMode getAvailability()

Returns the cache's availability. In local mode this method will always return AvailabilityMode.AVAILABLE. In clustered mode, the PartitionHandlingManager is queried to obtain the availability mode.

setAvailability

void setAvailability(AvailabilityMode availabilityMode)

Manually change the availability of the cache. Doesn't change anything if the cache is not clustered or PartitionHandlingConfiguration.whenSplit() is set to PartitionHandling.ALLOW_READ_WRITES.

cacheEntrySet

CacheSet<CacheEntry<K,V>> cacheEntrySet()

Identical to Cache.entrySet() but is typed to return CacheEntries instead of Entries. Please see the other method for a description of its behaviors.

This method is needed since nested generics do not support covariance

Returns:

the entry set containing all of the CacheEntries

See Also:

Cache.entrySet()

lockedStream

LockedStream<K,V> lockedStream()

Returns a sequential stream using this Cache as the source. This stream is very similar to using the CacheStream returned from the CacheCollection.stream() method of the collection returned via cacheEntrySet(). The use of this locked stream is that when an entry is being processed by the user the entry is locked for the invocation preventing a different thread from modifying it.

Note that this stream is not supported when using a optimistic transactional or simple cache. Both non transactional and pessimistic transactional caches are supported.

The stream will not share any ongoing transaction the user may have. Code executed by the stream should be treated as completely independent. That is any operation performed via the stream will require the user to start their own transaction or will be done intrinsically on the invocation. Note that if there is an ongoing transaction that has a lock on a key from the cache, that it will cause a deadlock.

Currently simple cache, ConfigurationBuilder.simpleCache(boolean) was set to true, and optimistic caches, TransactionConfigurationBuilder.lockingMode(LockingMode) was set to LockingMode.OPTIMISTIC, do not support this method. In this case it will throw an UnsupportedOperationException. This restriction may be removed in a future version. Also this method cannot be used on a cache that has a lock owner already specified via lockAs(Object) as this could lead to a deadlock or the release of locks early and will throw an IllegalStateException.

Returns:

the locked stream

Throws:

UnsupportedOperationException - this is thrown if invoked from a cache that doesn't support this

IllegalStateException - if this cache has already explicitly set a lock owner

removeLifespanExpired

CompletableFuture<Boolean> removeLifespanExpired(K key,
                                                 V value,
                                                 Long lifespan)

Attempts to remove the entry if it is expired. Due to expired entries not being consistent across nodes, this will still attempt to remove the value if it is not present. Note that this will raise an expired event even if the entry is not present. Normally this method should never be invoked except by the ExpirationManager.

This command will only remove the value if the value and lifespan also match if provided.

This method will suspend any ongoing transaction and start a new one just for the invocation of this command. It is automatically committed or rolled back after the command completes, either successfully or via an exception.

NOTE: This method may be removed at any point including in a minor release and is not supported for external usage.

Parameters:

key - the key that is expiring

value - the value that mapped to the given. Null means it will match any value

lifespan - the lifespan that should match. If null is provided it will match any lifespan value

Returns:

if the entry was removed

removeMaxIdleExpired

CompletableFuture<Boolean> removeMaxIdleExpired(K key,
                                                V value)

Attempts to remove the entry for the given key, if it has expired due to max idle. This command first locks the key and then verifies that the entry has expired via maxIdle across all nodes. If it has this will then remove the given key.

This method returns a boolean when it has determined if the entry has expired. This is useful for when a backup node invokes this command for a get that found the entry expired. This way the node can return back to the caller much faster when the entry is not expired and do any additional processing asynchronously if needed.

This method will suspend any ongoing transaction and start a new one just for the invocation of this command. It is automatically committed or rolled back after the command completes, either successfully or via an exception.

NOTE: This method may be removed at any point including in a minor release and is not supported for external usage.

Parameters:

key - the key that expired via max idle for the given entry

Returns:

if the entry was removed
