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 = new Function<Person, List<Address>>()
{
public List<Address> valueOf(Person person)
{
return 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);

MutableMapIt is imperative that the user manually synchronize on the returned map when iterating over any of its collection views:
MutableMap map = myMutableMap.asSynchronized();
...
Set set = map.keySet(); // Needn't be in synchronized block
...
synchronized(map)
{ // Synchronizing on map, not set!
Iterator i = s.iterator(); // Must be in 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.
MutableMap map = myMutableMap.asSynchronized();
...
Set set = map.keySet(); // Needn't be in synchronized block
...
Iterate.forEach(set, new Procedure()

MutableMap
map = map.withoutAllKeys(FastList.newListWith("key1", "key2"));
In the case of FixedSizeMap, a new instance will be returned by withoutAllKeys, and any variables that previously
referenced the original map will need to be redirected to reference the new instance. In the case of a FastMap
or UnifiedMap, you will be replacing the reference to map with map, since FastMap and UnifiedMap will both return
"this" after calling remove on themselves.withoutAllKeys in interface MutableMap<K,V>Map.remove(Object)public <K2,V2> MutableMap<K2,V2> aggregateInPlaceBy(Function<? super V,? extends K2> groupBy, Function0<? extends V2> zeroValueFactory, Procedure2<? super V2,? super V> mutatingAggregator)
