ClientTxnMultiMapProxy

public ClientTxnMultiMapProxy(String name,
                      ClientTransactionContext transactionContext)

Method Detail

put

public boolean put(K key,
          V value)
            throws TransactionException

Description copied from interface: TransactionalMultiMap

Stores a key-value pair in the multimap.

Specified by:

put in interface BaseMultiMap<K,V>

Specified by:

put in interface TransactionalMultiMap<K,V>

Parameters:

key - the key to be stored

value - the value to be stored

Returns:

true if the size of the multimap is increased, false if the multimap already contains the key-value pair.

Throws:

TransactionException

get

public Collection<V> get(K key)

Description copied from interface: TransactionalMultiMap

Returns the collection of values associated with the key.

Specified by:

get in interface BaseMultiMap<K,V>

Specified by:

get in interface TransactionalMultiMap<K,V>

Parameters:

key - the key whose associated values are returned

Returns:

the collection of the values associated with the key

remove

public boolean remove(Object key,
             Object value)

Description copied from interface: TransactionalMultiMap

Removes the given key value pair from the multimap.

Specified by:

remove in interface BaseMultiMap<K,V>

Specified by:

remove in interface TransactionalMultiMap<K,V>

Parameters:

key - the key of the entry to remove

value - the value of the entry to remove

Returns:

true if the size of the multimap changed after the remove operation, false otherwise.

remove

public Collection<V> remove(Object key)

Description copied from interface: TransactionalMultiMap

Removes all the entries associated with the given key.

Specified by:

remove in interface BaseMultiMap<K,V>

Specified by:

remove in interface TransactionalMultiMap<K,V>

Parameters:

key - the key of the entries to remove

Returns:

the collection of removed values associated with the given key. The returned collection might be modifiable but it has no effect on the multimap.

valueCount

public int valueCount(K key)

Description copied from interface: TransactionalMultiMap

Returns the number of values matching the given key in the multimap.

Specified by:

valueCount in interface BaseMultiMap<K,V>

Specified by:

valueCount in interface TransactionalMultiMap<K,V>

Parameters:

key - the key whose number of values is to be returned

Returns:

the number of values matching the given key in the multimap

size

public int size()

Description copied from interface: TransactionalMultiMap

Returns the number of key-value pairs in the multimap.

Specified by:

size in interface BaseMultiMap<K,V>

Specified by:

size in interface TransactionalMultiMap<K,V>

Returns:

the number of key-value pairs in the multimap

getServiceName

public String getServiceName()

Description copied from interface: DistributedObject

Returns the service name for this object.

Specified by:

getServiceName in interface DistributedObject

Returns:

the service name for this object.

getTransactionId

protected String getTransactionId()

destroy

public final void destroy()

Description copied from interface: DistributedObject

Destroys this object cluster-wide. Clears and releases all resources for this object.

Specified by:

destroy in interface DistributedObject

getName

public String getName()

Description copied from interface: DistributedObject

Returns the unique name for this DistributedObject. The returned value will never be null. The suggested way for getting name is retrieving it through DistributedObjectUtil.getName(DistributedObject) because this might be also a PrefixedDistributedObject.

Specified by:

getName in interface DistributedObject

Returns:

the unique name for this object.

getPartitionKey

public String getPartitionKey()

Description copied from interface: DistributedObject

Returns the key of the partition that this DistributedObject is assigned to. The returned value only has meaning for a non-partitioned data structure like an IAtomicLong. For a partitioned data structure like an IMap, the returned value will not be null, but otherwise undefined.

Specified by:

getPartitionKey in interface DistributedObject

Returns:

the partition key.
