Hides com.google.common.collect.ImmutableMultimap.builder.

Returns a new builder. The generated builder is equivalent to the builder created by the Builder constructor.

Hides com.google.common.collect.ImmutableMultimap.copyOf.

Returns an immutable multimap containing the same mappings as multimap. The generated multimap's key and value orderings correspond to the iteration ordering of the multimap.asMap() view.

Despite the method name, this method attempts to avoid actually copying the data when it is safe to do so. The exact circumstances under which a copy will or will not be performed are undocumented and subject to change.

Exceptions

NullPointerException:

if any key or value in multimap is null

Hides com.google.common.collect.ImmutableMultimap.copyOf.

Returns an immutable multimap containing the specified entries. The returned multimap iterates over keys in the order they were first encountered in the input, and the values for each key are iterated in the order they were encountered.

Exceptions

NullPointerException:

if any key, value, or entry is null

Returns a Collector accumulating entries into an ImmutableListMultimap. Each input element is mapped to a key and a stream of values, each of which are put into the resulting Multimap, in the encounter order of the stream and the encounter order of the streams of values.

Example:

static final ImmutableListMultimap<Character, Character> FIRST_LETTER_MULTIMAP =
    Stream.of("banana", "apple", "carrot", "asparagus", "cherry")
        .collect(
            flatteningToImmutableListMultimap(
                 str -> str.charAt(0),
                 str -> str.substring(1).chars().mapToObj(c -> (char) c));

// is equivalent to

static final ImmutableListMultimap<Character, Character> FIRST_LETTER_MULTIMAP =
    ImmutableListMultimap.<Character, Character>builder()
        .putAll('b', Arrays.asList('a', 'n', 'a', 'n', 'a'))
        .putAll('a', Arrays.asList('p', 'p', 'l', 'e'))
        .putAll('c', Arrays.asList('a', 'r', 'r', 'o', 't'))
        .putAll('a', Arrays.asList('s', 'p', 'a', 'r', 'a', 'g', 'u', 's'))
        .putAll('c', Arrays.asList('h', 'e', 'r', 'r', 'y'))
        .build();

Implements abstract com.google.common.collect.ImmutableMultimap.get.

Implements com.google.common.collect.ListMultimap.get, com.google.common.collect.Multimap.get.

Returns an immutable list of the values for the given key. If no mappings in the multimap have the provided key, an empty immutable list is returned. The values are in the same order as the parameters used to build this multimap.

Implements abstract com.google.common.collect.ImmutableMultimap.inverse.

Doc from com.google.common.collect.ImmutableMultimap.inverse.

Returns an immutable multimap which is the inverse of this one. For every key-value mapping in the original, the result will have a mapping with key and value reversed.

Because an inverse of a list multimap can contain multiple pairs with the same key and value, this method returns an ImmutableListMultimap rather than the ImmutableMultimap specified in the ImmutableMultimap class.

Returns a Collector that accumulates elements into an ImmutableListMultimap whose keys and values are the result of applying the provided mapping functions to the input elements.

For streams with defined encounter order (as defined in the Ordering section of the java.util.stream Javadoc), that order is preserved, but entries are grouped by key.

Example:

static final Multimap<Character, String> FIRST_LETTER_MULTIMAP =
    Stream.of("banana", "apple", "carrot", "asparagus", "cherry")
        .collect(toImmutableListMultimap(str -> str.charAt(0), str -> str.substring(1)));

// is equivalent to

static final Multimap<Character, String> FIRST_LETTER_MULTIMAP =
    new ImmutableListMultimap.Builder<Character, String>()
        .put('b', "anana")
        .putAll('a', "pple", "sparagus")
        .putAll('c', "arrot", "herry")
        .build();
