@Target(value={METHOD,FIELD})
@Retention(value=RUNTIME)
public @interface Version
This annotation specifies the version field or property of an entity class that serves as its
optimistic lock value. The version is used to ensure integrity when performing the merge
operation and for optimistic concurrency control.
Only a single Version property or field should be used per class; applications that use more
than one Version property or field will not be portable.
The Version property should be mapped to the primary table for the entity class; applications
that map the Version property to a table other than the primary table will not be portable.
The following types are supported for version properties: int, Integer, short, Short, long,
Long, Timestamp.
