    • flatCollect

      public <VV> MutableBag<VV> flatCollect(Function<? super V,? extends Iterable<VV>> 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);
