flip

public ImmutableSortedSetMultimap<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.

flatCollect

public <R> ImmutableList<R> flatCollect(Function<? super V,? extends Iterable<R>> function)

Description copied from interface: 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);
