55 * This class is an event container and holds a map of the events for an entire Apex model. All Apex models that use
56 * events must have an {@link AxEvents} field. The {@link AxEvents} class implements the helper methods of the
57 * {@link AxConceptGetter} interface to allow {@link AxEvents} instances to be retrieved by calling methods directly on
58 * this class without referencing the contained map.
60 * <p>Validation checks that the container key is not null. An error is issued if no events are defined in the
61 * container. Each event entry is checked to ensure that its key and value are not null and that the key matches the key
62 * in the map value. Each event entry is then validated individually.
