MutableMapIterableCollections.synchronizedMap(this) only with the more feature rich return type of
MutableMapIterable.
The preferred way of iterating over a synchronized map is to use the forEachKey(), forEachValue() and forEachKeyValue() methods which are properly synchronized internally.
MutableMap synchedMap = map.asSynchronized(); synchedMap.forEachKey(key -> ... ); synchedMap.forEachValue(value -> ... ); synchedMap.forEachKeyValue((key, value) -> ... );
If you want to iterate imperatively over the keySet(), values(), or entrySet(), you will need to protect the iteration by wrapping the code in a synchronized block on the map.
asSynchronized in interface MutableMap<K,V>asSynchronized in interface MutableMapIterable<K,V>Collections.synchronizedMap(Map)public MutableSetMultimap<V,K> flip()
MapIterable-> Range return a multimap from Range -> Domain. We chose the name 'flip'
rather than 'invert' or 'transpose' since this method does not have the property of applying twice
returns the original.
Since the keys in the input are unique, the values in the output are unique, so the return type should be a SetMultimap. However since SetMultimap and SortedSetMultimap don't inherit from one another, SetMultimap here does not allow SortedMapIterable to have a SortedSetMultimap return. Thus we compromise and call this Multimap, even though all implementations will be a SetMultimap or SortedSetMultimap.

MutableMapIterable
map = map.withKeyValue("new key", "new value");
In the case of FixedSizeMap, a new instance will be returned by withKeyValue, and any variables that
previously referenced the original map will need to be redirected to reference the new instance. In the case
of a FastMap or UnifiedMap, you will be replacing the reference to map with map, since FastMap and UnifiedMap
will both return "this" after calling put on themselves.withKeyValue in interface MutableMap<K,V>withKeyValue in interface MutableMapIterable<K,V>Map.put(Object, Object)public MutableMap<K,V> withAllKeyValues(Iterable<? extends Pair<? extends K,? extends V>> keyValues)

RichIterableExample using a Java 8 method reference:
Multimap<String, Person> peopleByLastName =
people.groupBy(Person::getLastName);
Example using an anonymous inner class:
Multimap<String, Person> peopleByLastName =
people.groupBy(new Function<Person, String>()
{
public String valueOf(Person person)
{
return person.getLastName();
}
});
