Interface ParentedFacet

All Superinterfaces:

Facet, MarkerFacet

All Known Implementing Classes:

ParentedFacetAbstract, ParentedFacetSinceAggregatedAnnotation, ParentedFacetSinceCollection

public interface ParentedFacet
extends MarkerFacet

Indicates that this class is parented, that is, wholly contained within a larger object.

There are two classes of object that are parented:

• Aggregated objects
• Internal collections

In the standard Apache Isis Programming Model, aggregated objects typically corresponds to applying the @Aggregated annotation at the class level. In terms of an analogy, aggregated is similar to Hibernate's component types (for larger mutable in-line objects) or to Hibernate's user-defined types (for smaller immutable values).

Internal collections are the Lists, Sets etc that hold references to other root entities.

The object may or may not be immutable. If an aggregated entity, then it may reference regular entity domain objects or other aggregated objects.
