Feature overview
This feature is about determining the content of Dali JAXB projects.
Goals:
- Add JAXB annotated classes to project content
- Add JAXB annotated packages to project content
- Add statically referenced classes to project content
- Add user specified default annotated packages and classes to project content
- Add support for jaxb.index
- Add support for ObjectFactory classes
- Add external packages and classes to project content
Concepts
Unlike JPA, the context of a JAXB 'project' (the JAXBContext) is determined dynamically at runtime, not dev-time. The user determines what is included when he creates the JAXBContext object. In addition, JAXB classes and packages do not have to be annotated - defaults abound! - so determining what classes are intended for JAXB use without having that information is tricky.
A user may pass in a list of packages, or a list of classes, or a combination. In addition to those packages and classes, any statically referenced classes are also brought in. (e.g. If Foo has a mapping to Bar, then Bar is also brought in, but if Foo is only extended by Bar, then it is not; it has no actual reference to Bar.)
When a package is passed in, a jaxb.index or ObjectFactory is used to determine the specific classes that are to be brought in. The jaxb.index is a return-separated list of classes. Any classes statically referenced by the ObjectFactory are brought in.
