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 = 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);
