Method Detail

containsKeyAsync

public RFuture<Boolean> containsKeyAsync(Object key)

Description copied from interface: RMultimapAsync

Returns true if this multimap contains at least one key-value pair with the key key.

Specified by:

containsKeyAsync in interface RMultimapAsync<K,V>

Overrides:

containsKeyAsync in class RedissonSetMultimap<K,V>

Parameters:

key - - map key

Returns:

true if contains a key

containsValueAsync

public RFuture<Boolean> containsValueAsync(Object value)

Description copied from interface: RMultimapAsync

Returns true if this multimap contains at least one key-value pair with the value value.

Specified by:

containsValueAsync in interface RMultimapAsync<K,V>

Overrides:

containsValueAsync in class RedissonSetMultimap<K,V>

Parameters:

value - - map value

Returns:

true if contains a value

containsEntryAsync

public RFuture<Boolean> containsEntryAsync(Object key,
                                  Object value)

Description copied from interface: RMultimapAsync

Returns true if this multimap contains at least one key-value pair with the key key and the value value.

Specified by:

containsEntryAsync in interface RMultimapAsync<K,V>

Overrides:

containsEntryAsync in class RedissonSetMultimap<K,V>

Parameters:

key - - map key

value - - map value

Returns:

true if contains an entry

get

public RSet<V> get(K key)

Description copied from interface: RSetMultimap

Returns a view collection of the values associated with key in this multimap, if any. Note that when containsKey(key) is false, this returns an empty collection, not null.

Changes to the returned collection will update the underlying multimap, and vice versa.

Because a RSetMultiMap has unique values for a given key, this method returns a Set, instead of the Collection specified in the RMultimap interface.

Specified by:

get in interface RMultimap<K,V>

Specified by:

get in interface RSetMultimap<K,V>

Overrides:

get in class RedissonSetMultimap<K,V>

Parameters:

key - - map key

Returns:

collection of values

getAllAsync

public RFuture<Collection<V>> getAllAsync(K key)

Specified by:

getAllAsync in interface RMultimapAsync<K,V>

Overrides:

getAllAsync in class RedissonSetMultimap<K,V>

removeAllAsync

public RFuture<Collection<V>> removeAllAsync(Object key)

Description copied from interface: RMultimapAsync

Removes all values associated with the key key.

Once this method returns, key will not be mapped to any values.

Specified by:

removeAllAsync in interface RMultimapAsync<K,V>

Overrides:

removeAllAsync in class RedissonSetMultimap<K,V>

Parameters:

key - - map key

Returns:

the values that were removed (possibly empty). The returned collection may be modifiable, but updating it will have no effect on the multimap.

                long timeToLive,
                TimeUnit timeUnit)

expireKey in interface RMultimapCache<K,V>

Parameters:

key - - map key
