buri.ddmsence.util.LazyList

Utility class for a list with dynamically added contents.

LazyList wraps around a standard ArrayList and ensures that any get() activity which returns a null value will return a freshly instantiated item instead.

This class should allow the Component Builder framework to function well within a form-based UI, where child components are added / removed at the web page level.

This class is similar in intent to the Apache commons-collections version, but my implementation differs in the following ways:

Simplified layers of abstraction.
Eliminated overhead of Factory boilerplate to instantiate new items. Classes can just be instantiated through the basic no-arg constructor.
Interim positions are also instantiated when an index beyond the size of the list is requested.
