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);

MutableSortedBagasUnmodifiable in interface MutableSortedBag<T>asUnmodifiable in interface MutableCollection<T>public MutableSortedBag<T> asSynchronized()
MutableCollectionIt is imperative that the user manually synchronize on the returned collection when iterating over it using the standard JDK iterator or JDK 5 for loop.
MutableCollection collection = myCollection.asSynchronized();
...
synchronized(collection)
{
Iterator i = c.iterator(); // Must be in the synchronized block
while (i.hasNext())
foo(i.next());
}
Failure to follow this advice may result in non-deterministic behavior.
The preferred way of iterating over a synchronized collection is to use the collection.forEach() method which is properly synchronized internally.
MutableCollection collection = myCollection.asSynchronized();
...
collection.forEach(new Procedure()
{
public void value(Object each)
{
...
}
});
The returned collection does not pass the hashCode and equals operations through to the backing collection, but relies on Object's equals and hashCode methods. This is necessary to preserve the contracts of these operations in the case that the backing collection is a set or a list.
The returned collection will be serializable if this collection is serializable.
