    • 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>
        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>
        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>
        Parameters:
        key - - map key
        value - - map value
        Returns:
        true if contains an entry
      • putAsync

        public RFuture<Boolean> putAsync​(K key,
                                         V value)
        Description copied from interface: RMultimapAsync
        Stores a key-value pair in this multimap.

        Some multimap implementations allow duplicate key-value pairs, in which case put always adds a new key-value pair and increases the multimap size by 1. Other implementations prohibit duplicates, and storing a key-value pair that's already in the multimap has no effect.

        Specified by:
        putAsync in interface RMultimapAsync<K,​V>
        Parameters:
        key - - map key
        value - - map value
        Returns:
        true if the method increased the size of the multimap, or false if the multimap already contained the key-value pair and doesn't allow duplicates
      • removeAsync

        public RFuture<Boolean> removeAsync​(Object key,
                                            Object value)
        Description copied from interface: RMultimapAsync
        Removes a single key-value pair with the key key and the value value from this multimap, if such exists. If multiple key-value pairs in the multimap fit this description, which one is removed is unspecified.
        Specified by:
        removeAsync in interface RMultimapAsync<K,​V>
        Parameters:
        key - - map key
        value - - map value
        Returns:
        true if the multimap changed
      • putAllAsync

        public RFuture<Boolean> putAllAsync​(K key,
                                            Iterable<? extends V> values)
        Description copied from interface: RMultimapAsync
        Stores a key-value pair in this multimap for each of values, all using the same key, key. Equivalent to (but expected to be more efficient than):
           
        
           for (V value : values) {
             put(key, value);
           }

        In particular, this is a no-op if values is empty.

        Specified by:
        putAllAsync in interface RMultimapAsync<K,​V>
        Parameters:
        key - - map key
        values - - map values
        Returns:
        true if the multimap changed
      • 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>
        Parameters:
        key - - map key
        Returns:
        collection of values
      • getAll

        public Set<V> getAll​(K key)
        Description copied from interface: RMultimap
        Returns all elements at once. Result collection is NOT backed by map, so changes are not reflected in map.
        Specified by:
        getAll in interface RMultimap<K,​V>
        Specified by:
        getAll in interface RSetMultimap<K,​V>
        Overrides:
        getAll in class RedissonMultimap<K,​V>
        Parameters:
        key - - map key
        Returns:
        collection of values
      • removeAll

        public Set<V> removeAll​(Object key)
        Description copied from interface: RMultimap
        Removes all values associated with the key key.

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

        Use RMultimap.fastRemove(K...) if values are not needed.

        Specified by:
        removeAll in interface RMultimap<K,​V>
        Specified by:
        removeAll in interface RSetMultimap<K,​V>
        Overrides:
        removeAll in class RedissonMultimap<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.
      • 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>
        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.
      • entries

        public Set<Map.Entry<K,​V>> entries()
        Description copied from interface: RMultimap
        Returns a view collection of all key-value pairs contained in this multimap, as Map.Entry instances.

        Changes to the returned collection or the entries it contains will update the underlying multimap, and vice versa. However, adding to the returned collection is not possible.

        Specified by:
        entries in interface RMultimap<K,​V>
        Specified by:
        entries in interface RSetMultimap<K,​V>
        Overrides:
        entries in class RedissonMultimap<K,​V>
        Returns:
        collection of entries
      • replaceValues

        public Set<V> replaceValues​(K key,
                                    Iterable<? extends V> values)
        Description copied from interface: RMultimap
        Stores a collection of values with the same key, replacing any existing values for that key.

        If values is empty, this is equivalent to removeAll(key).

        Specified by:
        replaceValues in interface RMultimap<K,​V>
        Specified by:
        replaceValues in interface RSetMultimap<K,​V>
        Overrides:
        replaceValues in class RedissonMultimap<K,​V>
        Parameters:
        key - - map key
        values - - map values
        Returns:
        the collection of replaced values, or an empty collection if no values were previously associated with the key. The collection may be modifiable, but updating it will have no effect on the multimap.
      • replaceValuesAsync

        public RFuture<Collection<V>> replaceValuesAsync​(K key,
                                                         Iterable<? extends V> values)
        Description copied from interface: RMultimapAsync
        Stores a collection of values with the same key, replacing any existing values for that key.

        If values is empty, this is equivalent to RMultimapAsync.removeAllAsync(Object).

        Specified by:
        replaceValuesAsync in interface RMultimapAsync<K,​V>
        Parameters:
        key - - map key
        values - - map values
        Returns:
        the collection of replaced values, or an empty collection if no values were previously associated with the key. The collection may be modifiable, but updating it will have no effect on the multimap.
