Method Detail

put

boolean put(K key,
            V value)
Stores a key-value pair in the multimap.

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.

get

Collection<V> get(K key)
Returns the collection of values associated with the key.

Parameters:
key - the key whose associated values are returned
Returns:
the collection of the values associated with the key

remove

boolean remove(Object key,
               Object value)
Removes the given key value pair from the multimap.

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

Collection<V> remove(Object key)
Removes all the entries associated with the given key.

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

int valueCount(K key)
Returns the number of values matching the given key in the multimap.

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

int size()
Returns the number of key-value pairs in the multimap.

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