Events

Events represent a system modification.

An event is a class inheriting from IEvent<>. It contains:

• basic type parameters
• a method which should call a method on an aggregate.

Example:

    public class DummyModificationEvent : IEvent<DummyAggregate>
    {
        public string Value { get; set; }

        public void Apply(DummyAggregate aggregate, IEventInformation information)
        {
            aggregate.Modify(information.Type(this));
        }

        public string AggregateId { get; set; }
    }

An event represent something that already happened. An aggregate cannot refuse an event, and an event must call an aggregate method.
