This class provides a MutableList wrapper around a JDK Collections ArrayList instance. All of the MutableList
interface methods are supported in addition to the JDK ArrayList methods.
To create a new wrapper around an existing ArrayList instance, use the adapt(ArrayList<Object>)
factory method. To create a new empty wrapper, use the newList()
or newList(int)
factory methods.
