    • Method Detail

      • put

        public ImmutableHashTrieMap<K,​V> put​(K key,
                                                   V value)
        Description copied from interface: ImmutableMap
        Add a new entry to the map. If an entry already exists with the given key, the returned map will contain this entry, but not the existing entry.
        Specified by:
        put in interface ImmutableMap<K,​V>
        Parameters:
        key - the key to use to retrieve this item
        value - the value stored for this item
        Returns:
        a new map with this item added
      • remove

        public ImmutableHashTrieMap<K,​V> remove​(K key)
        Description copied from interface: ImmutableMap
        Remove an entry from the map. If no entry exists with the given key, the returned map will have identical contents to the original map (and may, in fact, be the original map itself).
        Specified by:
        remove in interface ImmutableMap<K,​V>
        Parameters:
        key - the key for the entry to remove
        Returns:
        a new map with the entry with the given key removed (or a map with the original contents if no entry was found for the given key).
      • get

        public V get​(K key)
        Description copied from interface: ImmutableMap
        Retrieve a stored value from the map based on the key for the associated entry. If no entry exists with the given key, we return None.
        Specified by:
        get in interface ImmutableMap<K,​V>
        Parameters:
        key - the key for the entry to retrieve
        Returns:
        Some(value) if an entry exists with the given key, or None if no entry with the given key was found.
