@Immutable public interface ImmutableSet<T> extends UnsortedSetIterable<T>, ImmutableSetIterable<T>
MutableSet
. MutableSet.toImmutable()
will
give you an appropriately trimmed implementation of ImmutableSet. All ImmutableSet implementations must implement
the java.util.Set interface so they can satisfy the equals() contract and be compared against other set structures
like UnifiedSet or HashSet.Modifier and Type | Method and Description |

flatCollect
is a special case of RichIterable.collect(Function)

, 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; MutableList<Person> people = ...;Using
collect
returns a collection of collections of addresses.
MutableList<List<Address>> addresses = people.collect(addressFunction);Using
flatCollect
returns a single flattened list of addresses.
MutableList<Address> addresses = people.flatCollect(addressFunction);
