public @interface TypeConverter
```
The TypeConverter annotation is used to specify an EclipseLink org.eclipse.persistence.mappings.converters.TypeConversionConverter for modification of the data value(s) during the reading and writing of a mapped attribute. A TypeConverter 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 an TypeConverter is always specified via the Convert annotation and is supported on a Basic, or ElementCollection mapping.
