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.

methods which are properly synchronized internally.
MutableCollection synchedCollection = collection.asSynchronized(); ... synchedCollection.forEach(each -> ... ); synchedCollection.select(each -> ... ); synchedCollection.collect(each -> ... );If you want to iterate using an imperative style, you must protect external iterators using a synchronized block. This includes explicit iterators as well as JDK 5 style for loops.
