Method Detail

getName

public String getName()

Description copied from interface: DistributedObject

Returns the unique name for this DistributedObject. The returned value will never be null.

Specified by:

getName in interface DistributedObject

Returns:

the unique name for this object.

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.

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

toString
