[saga-rg] Is there Factory in Java Binding?

[Hidemoto Nakada]

All,

I have a question on the Java Binding.
Does the current Java binding include explicit factory notion?

Factory mechanism is important to
- reuse a source code with several implementation of the API
   without modification of the code.
- leverage several implementation simultaneously from one
  client code.

One good example of factory design can be found in the Dom parser
definition; org.w3c.dom.DomImplementation.
When you create a Dom document

- get a DomImplementation from org.w3c.dom.bootstrap.DomImplementationRegistory
- then create a Document object using DomImplementation.

This mechanism might be too complicated for SAGA, but
I think some flavor of this is required.
