ReadMostlyVector (Jersey 2.22 API)

java.lang.Object
- jersey.repackaged.jsr166e.extra.ReadMostlyVector<E>

All Implemented Interfaces:

Serializable, Cloneable, Iterable<E>, Collection<E>, List<E>, RandomAccess
```
public class ReadMostlyVector<E>
extends Object
implements List<E>, RandomAccess, Cloneable, Serializable
```
A class with the same methods and array-based characteristics as Vector but with reduced contention and improved throughput when invocations of read-only methods by multiple threads are most common.
The iterators returned by this class's iterator and listIterator methods are best-effort in the presence of concurrent modifications, and do NOT throw ConcurrentModificationException. An iterator's next() method returns consecutive elements as they appear in the underlying array upon each access. Alternatively, method snapshotIterator() may be used for deterministic traversals, at the expense of making a copy, and unavailability of method Iterator.remove.
Otherwise, this class supports all methods, under the same documented specifications, as Vector. Consult Vector for detailed specifications. Additionally, this class provides methods addIfAbsent(E) and addAllAbsent(java.util.Collection<? extends E>).

```
public ReadMostlyVector(int initialCapacity,
