Interface Relation<S extends Resource,T extends Entity>

Type Parameters:
S - The type of the source resource.
T - The type of the target entity.
All Superinterfaces:
Element, ERElement, IdentifiableElement, ModelElement, RelationElement<S,T>, SchemaMixedElement, Serializable
All Known Subinterfaces:
ConsistsOf<S,T>, IsRelatedTo<S,T>
All Known Implementing Classes:
ConsistsOfImpl, DummyIsRelatedTo, IsRelatedToImpl, RelationImpl
@TypeMetadata(name="Relation", description="This is the base type for any Relation", version="1.0.0") @Change(version="1.0.0", description="First Version") public interface Relation<S extends Resource,T extends Entity> extends RelationElement<S,T>, SchemaMixedElement, ERElement
The base interface for all relations in the facet-based resource model.

A relation connects a source Resource to a target Entity and can have its own properties. It supports schema-mixed mode for additional attributes. For more details, refer to the gCube Facet Based Resource Model Wiki.
