A builder for creating immutable SetMultimap instances, especially public static final multimaps ("constant multimaps"). Example: static final Multimap STRING_TO_INTEGER_MULTIMAP = new ImmutableSetMultimap.Builder() .put("one", 1) .putAll("several", 1, 2, 3) .putAll("many", 1, 2, 3, 4, 5) .build(); Builder instances can be reused; it is safe to call #build multiple times to build multiple multimaps in series. Each multimap contains the key-value mappings in the previously created multimaps.
A SetMultimap<K,V> whose contents will never change, with many other important properties detailed at ImmutableCollection<E>. See the Guava User Guide article on immutable collections.
An implementation of ListMultimap that supports deterministic iteration order for both keys and values. The iteration order is preserved across non-distinct key values. For example, for the following multimap definition: Multimap multimap = LinkedListMultimap.create(); multimap.put(key1, foo); multimap.put(key2, bar); multimap.put(key1, baz); ... the iteration order for #keys() is [key1, key2, key1], and similarly for entries(). Unlike LinkedHashMultimap<K,V>, the iteration order is kept consistent between keys, entries and values. For example, calling: map.remove(key1, foo); changes the entries iteration order to [key2=bar, key1=baz] and the key iteration order to [key2, key1]. The entries() iterator returns mutable map entries, and #replaceValues attempts to preserve iteration order as much as possible. The collections returned by #keySet() and #asMap iterate through the keys in the order they were first added to the multimap. Similarly, #get, #removeAll, and #replaceValues return collections that iterate through the values in the order they were added. The collections generated by entries(), #keys(), and #values iterate across the key-value mappings in the order they were added to the multimap. The values() and entries() methods both return a List, instead of the Collection specified by the ListMultimap<K,V> interface. The methods #get, #keySet(), #keys(), #values, entries(), and #asMap return collections that are views of the multimap. If the multimap is modified while an iteration over any of those collections is in progress, except through the iterator's methods, the results of the iteration are undefined. Keys and values may be null. All optional multimap methods are supported, and all returned views are modifiable. This class is not threadsafe when any concurrent operations update the multimap. Concurrent read operations will work correctly. To allow concurrent update operations, wrap your multimap with a call to Multimaps#synchronizedListMultimap. See the Guava User Guide article on Multimap.
A builder for creating immutable bimap instances, especially public static final bimaps ("constant bimaps"). Example: static final ImmutableBiMap WORD_TO_INT = new ImmutableBiMap.Builder() .put("one", 1) .put("two", 2) .put("three", 3) .build(); For small immutable bimaps, the ImmutableBiMap.of() methods are even more convenient. By default, a Builder will generate bimaps that iterate over entries in the order they were inserted into the builder. For example, in the above example, WORD_TO_INT.entrySet() is guaranteed to iterate over the entries in the order "one"=1, "two"=2, "three"=3, and keySet() and values() respect the same order. If you want a different order, consider using orderEntriesByValue(Comparator<? super V> valueComparator), which changes this builder to sort entries by value. Builder instances can be reused - it is safe to call #build multiple times to build multiple bimaps in series. Each bimap is a superset of the bimaps created before it.
An object representing the differences between two maps.
A Multimap that cannot hold duplicate key-value pairs. Adding a key-value pair that's already in the multimap has no effect. See the Multimap<K,V> documentation for information common to all multimaps. The #get, #removeAll, and #replaceValues methods each return a Set of values, while #entries returns a Set of map entries. Though the method signature doesn't say so explicitly, the map returned by #asMap has Set values. If the values corresponding to a single key should be ordered according to a java.util.Comparator (or the natural order), see the SortedSetMultimap<K,V> subinterface. Since the value collections are sets, the behavior of a SetMultimap is not specified if key or value objects already present in the multimap change in a manner that affects equals comparisons. Use caution if mutable objects are used as keys or values in a SetMultimap. See the Guava User Guide article on Multimap.
A Map whose contents will never change, with many other important properties detailed at ImmutableCollection<E>. See the Guava User Guide article on immutable collections.
A ListMultimap<K,V> whose contents will never change, with many other important properties detailed at ImmutableCollection<E>. See the Guava User Guide article on immutable collections.
A list multimap which forwards all its method calls to another list multimap. Subclasses should override one or more methods to modify the behavior of the backing multimap as desired per the decorator pattern. default method warning: This class does not forward calls to default methods. Instead, it inherits their default implementations. When those implementations invoke methods, they invoke methods on the ForwardingListMultimap.
