Modeling Aggregates, Entities and Value Objects

Complex Heart allows you to model your domain Aggregates, Entities, and Value Objects using a set of traits. Great, but why traits and not classes? Well, sometimes you have some kind of inheritance in your classes. Being forced to use a certain base class is too invasive and personally, I don't like it. By using a set of traits and interfaces you have all the functionality you need without compromising the essence of your own domain.

The available traits are:

  • HasAttributes Provide some functionality to manage attributes.
  • HasEquality Provide functionality to handle equality between objects.
  • HasInvariants Allow invariant checking on instantiation (Guard Clause).
  • HasIdentity Define the Entity/Aggregate identity.
  • HasDomainEvents Provide domain event management.

On top of those base traits Complex Heart provide ready to use compositions:

  • IsModel composed by HasAttributes and HasInvariants.
  • IsValueObject composed by IsModel and HasEquality.
  • IsEntity composed by IsModel, HasIdentity, HasEquality.
  • IsAggregate composed by IsEntity, HasDomainEvents.
