public @interface Converter
A Converter is used to customize the values during the reading from the
database into the object model as well as during the writing back of changes
into the database. This annotation allows developers to define a named
converter that can be used in their mappings. A converter can be defined on
an entity class, method, or field.
A Converter must be be uniquely identified by name and can be defined at
the class, field and property level and can be specified within an Entity,
MappedSuperclass and Embeddable class.
The usage of a Converter is always specified via the Convert annotation and
is supported on a Basic, BasicMap or BasicCollection mapping.
