MutableMapIterable
Collections.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.

public MutableListMultimap<V,K> flip()
MapIterable
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.

public <R> MutableList<R> flatCollect(Function<? super V,? extends java.lang.Iterable<R>> function)
RichIterable
flatCollect
is a special case of RichIterable.collect(Function)
. With collect
, when the Function
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 each Person
has a list of Address
objects. Take the following Function
:
Function<Person, List<Address>> addressFunction = Person::getAddresses; RichIterable<Person> people = ...;Using
collect
returns a collection of collections of addresses.
RichIterable<List<Address>> addresses = people.collect(addressFunction);Using
flatCollect
returns a single flattened list of addresses.
RichIterable<Address> addresses = people.flatCollect(addressFunction);
