public class ArrayList4<E>
extends AbstractList4<E>
implements java.lang.Cloneable, java.io.Serializable, java.util.RandomAccess, Activatable
```
Transparent activatable ArrayList implementation. Implements List interface using an array to store elements. Each ArrayList4 instance has a capacity, which indicates the size of the internal array.

When instantiated as a result of a query, all the internal members are NOT activated at all. When internal members are required to perform an operation, the instance transparently activates all the members.
