/**
 * @fileoverview Representation of an enum.
 */


/**
 * @class
 * Base interface for all enum objects.
 * This class allows containers to use constants for fields that are usually
 * have a common set of values.
 * There are two main ways to use this class.
 *
 * <p>
 * If your gadget just wants to display how much of a smoker someone is,
 * it can simply use:
 * </p>
 *
 * <pre>html = "This person smokes: " + person.getField('smoker').getValue();</pre>
 *
 * <p>
 * This value field will be correctly set up by the container. This is a place
 * where the container can even localize the value for the gadget so that it
 * always shows the right thing.
 * </p>
 *
 * <p>
 * If your gadget wants to have some logic around the smoker
 * field it can use:
 * </p>
 *
 * <pre>if (person.getField('smoker').getKey() != "NO") { //gadget logic here }</pre>
 *
 * <p class="note">
 * <b>Note:</b>
 * The key may be null if the person's smoker field cannot be coerced
 * into one of the standard enum types.
 * The value, on the other hand, is never null.
 * </p>
