@NotThreadSafe public class FastList<T> extends AbstractMutableList<T> implements Externalizable, RandomAccess, BatchIterable<T>
An empty FastList created by calling the default constructor starts with a shared reference to a static empty array (DEFAULT_SIZED_EMPTY_ARRAY). This makes empty FastLists very memory efficient. The first call to add will lazily create an array of size 10.
An empty FastList created by calling the pre-size constructor with a value of 0 (new FastList(0)) starts with a shared reference to a static empty array (ZERO_SIZED_ARRAY). This makes FastLists presized to 0 very memory efficient as well. The first call to add will lazily create an array of size 1.

, when the Function
returns
a collection, the result is a collection of collections. flatCollect
outputs a single "flattened" collection

has a list of Address
objects. Take the following Function
:
