public class DTOFactory

extends java.lang.Object

The DTOFactory is a utility class that centralizes the code that converts a data transfer objects (DTOs) into value objects. Value objects are representations of the domain, similar but very much simpler than the actual entity beans they are associated with. DTOs on the other hand are the client's view of the beans.

For each bean we need an object that can transfer the bean attributes from the service to the entity, in the case of Container Manager Relations we do not include associated bean information in the DTO.

Since a service may need to work with several entity beans it is therefore necessary to centralize the code to create the DTOs, otherwise we risk having duplicate code spread over the services. This class is designed to do exactly that.

As an extra there are method provided that will convert a collection of DTO objects into a collection of DTOs.

For better performance there are also some methods that allow working with arrays rather than Collection instances, A Collection implies a cast for each element, this typically is slow and error-prone. Arrays are type-safe. The DTOFactory is instantiated using the getInstance() method, there is no public constructor available.

There is also a Factory that works in the other direction: DataFactory
