public <V> ImmutableBag<V> flatCollect(Function<? super T,? extends Iterable<V>> 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; 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);

AbstractRichIterable
This implementation creates an empty string buffer, appends a left square bracket, and iterates over the collection appending the string representation of each element in turn. After appending each element except the last, the string ", " is appended. Finally a right bracket is appended. A string is obtained from the string buffer, and returned.
