public abstract class EnumClass<IdentifierType>
extends Object

The purpose of this abstract base class is to allow the creation of type-safe enumerations.

Only the derived class is allowed to create instances and should do so as public static final objects.

Each instance of a EnumClass class needs an identifier to its constructor. This identifier is used to uniquely differentiate enumeration members amongst each-other.
