Enhancer, enhancement

Hola persefone,
Estoy trabajando con un documento tecnico acerca de Java Data Objects (JDO) y me encuentro con una palabra que no se interpretar: ENHANCER, ENHANCEMENT. Ni con el traductor babylon y la mayoría de sus glosarios soy capaz de darle un significado que me aporte algo.
Te agradecería en el alma que me ayudases. Llevo ya un tiempo con ello y ando falto de tiempo para entregar un proyecto.
Te pongo unos ejemplos en donde aparece:
- Como titulo de una sección:
ENHANCEMENT vs. Hand-coding
¿ Por cierto, hand-coding tampoco se
traducirlo?
Whilst all JDO instances must implement the PersistenceCapable interface, and this is the primary purpose of ENHANCEMENT, JDO does not mandate that the ENHANCEMENT tool be used for this purpose. It is perfectly
legal for a developer to hand-code a class to implement the PersistenceCapable interface.
With the persistence descriptor written, the domain objects ENHANCED, the storage defined as required and
the application's invocation of the persistence manager written, the application is ready to run.
The flow of activities described for this simple example shows the application being written before the
ENHANCEMENT phase. In this case there is no dependency between these actions. However, where more complicated domain object models are being used and the ENHANCER is responsible for generating primary key classes, the ENHANCEMENT phase must be performed before the application can be compiled.
MUCHAS GRACIAS POR LAS MOLESTIAS
