withKeyValue
public MutableSortedMap<K,V> withKeyValue(K key, V value)
Description copied from interface:MutableMapIterable
This method allows mutable, fixed size, and immutable maps the ability to add elements to their existing elements. In order to support fixed size maps, a new instance of a map would have to be returned including the keys and values of the original plus the additional key and value. In the case of mutable maps, the original map is modified and then returned. In order to use this method properly with mutable and fixed size maps the following approach must be taken: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.- Specified by:

flip
public MutableSortedSetMultimap<V,K> flip()
Description copied from interface:MapIterable
Given a map from Domain->
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.

Description copied from interface:MutableMapIterable
Returns an unmodifiable view of this map. This is the equivalent of usingCollections.unmodifiableMap(this)

. Methods which would mutate the underlying map will throw UnsupportedOperationExceptions.- Specified by:

asSynchronized
public MutableSortedMap<K,V> asSynchronized()
Description copied from interface:MutableMapIterable
Returns a synchronized wrapper backed by this map. This is the equivalent of callingCollections.synchronizedMap(this)
only with the more feature rich return type ofMutableMapIterable
.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.

flatCollect
public <R> MutableList<R> flatCollect(Function<? super V,? extends java.lang.Iterable<R>> function)
Description copied from interface:RichIterable
flatCollect
is a special case ofRichIterable.collect(Function)
. Withcollect
, when theFunction
returns a collection, the result is a collection of collections.flatCollect
outputs a single "flattened" collection instead. This method is commonly called flatMap.Consider the following example where we have a
Person
class, and eachPerson
has a list ofAddress
objects. Take the followingFunction
:Function<Person, List<Address>> addressFunction = Person::getAddresses; RichIterable<Person> people = ...;
Usingcollect
returns a collection of collections of addresses.RichIterable<List<Address>> addresses = people.collect(addressFunction);
UsingflatCollect
returns a single flattened list of addresses.RichIterable<Address> addresses = people.flatCollect(addressFunction);
