@Immutable public interface ImmutableSet<T> extends ImmutableCollection<T>, UnsortedSetIterable<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 |

RichIterableflatCollect 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 = new Function<Person, List<Address>>()
{
public List<Address> valueOf(Person person)
{
return 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);
