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.

flatCollect returns a single flattened list of addresses.

integers.rejectWith(Predicates2.equal(), Integer.valueOf(5));

MutableCollectionRichIterable.collect(Function) with a Function2 and specified parameter which is passed to the block.
Example using a Java 8 lambda expression:
RichIterable<Integer> integers =
Lists.mutable.with(1, 2, 3).collectWith((each, parameter) -> each + parameter, Integer.valueOf(1));
Example using an anonymous inner class:
Function2<Integer, Integer, Integer> addParameterFunction =
new Function2<Integer, Integer, Integer>()
{
public Integer value(Integer each, Integer parameter)
{
return each + parameter;
}
};
RichIterable<Integer> integers =
Lists.mutable.with(1, 2, 3).collectWith(addParameterFunction, Integer.valueOf(1));
Co-variant example for MutableCollection:
MutableCollection<Integer> integers =
Lists.mutable.with(1, 2, 3).collectWith((each, parameter) -> each + parameter, Integer.valueOf(1));
