Examples of org.hibernate.type.Type

org.hibernate.type.Type
Defines a mapping between a Java type and one or more JDBC {@linkplain java.sql.Types types}, as well as describing the in-memory semantics of the given java type (how do we check it for 'dirtiness', how do we copy values, etc).
Application developers needing custom types can implement this interface (either directly or via subclassing an existing impl) or by the (slightly more stable, though more limited) {@link org.hibernate.usertype.UserType}interface.
Implementations of this interface must certainly be thread-safe. It is recommended that they be immutable as well, though that is difficult to achieve completely given the no-arg constructor requirement for custom types. @author Gavin King @author Steve Ebersole
