public interface DomainType<J>
Describes any type forming part of the application domain model.

This is the base type for Hibernate's extension of the standard metamodel of the JPA type system.

Encapsulates a JavaType describing the more rudimentary aspects of the Java type. The DomainType is a higher-level construct incorporating information such as bean properties, constructors, and so on.

Implementation Note:
The actual JPA type system is more akin to SimpleDomainType. This contract represents a "higher level" abstraction, allowing descriptors for collections (which JPA does not define) as well as Hibernate-specific features (like dynamic models and @Any).
