Annotation Interface Alias

@Documented
@Target({FIELD,METHOD})
@Retention(RUNTIME)
public @interface Alias

Annotation used on properties of an entity value that provide an alternative identifier to find the entity.

Finding an entity by alias is used both when looking for a child entity via Entity.getEntity(java.lang.Object), and when loading an entity (or aggregate) by entity id, e.g. using Fluxzero.loadAggregateFor(java.lang.Object, java.lang.Class<?>).

You can annotate fields and property methods. If a property value is a collection the members of the collection are all added as aliases of the entity. If the property value is null or an empty collection the alias is ignored.
