public MutableList<T> asSynchronized()
MutableCollection
It 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.

public MutableFloatList collectFloat(FloatFunction<? super T> floatFunction)
RichIterable
float
iterable with the results of applying the specified function on each element
of the source collection. This method is also commonly called transform or map.
Example using a Java 8 lambda expression:
FloatIterable floats = people.collectFloat(person -> person.getHeightInInches());
Example using an anonymous inner class:
FloatIterable floats = people.collectFloat(new FloatFunction<Person>() { public float floatValueOf(Person person) { return person.getHeightInInches(); } });

public <V> ArrayListAdapter<V> flatCollect(Function<? super T,? extends Iterable<V>> function)
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; 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);
