[jdom-interest] Factories for builders.

[Richard Cook]

I think this will be a nice addition to JDOM capability.

only a few very minor points

1. is there any value in having more lightweight interfaces (eg
ElementFactory, AttributeFactory) and JDOMFactory interface implements all
of them. This means I can use ElementFactory wherever I need such an
interface plugin but don't want to implement the whole JDOMFactory (though I
don't think this is of any value within JDOM itself).

2. Should the factory contain only a minimal set of methods - eg
Element(String,Namespace) rather than duplicate all constructors.

3. You could save a possible redundant creation of DefaultJDOMFactory by
putting it in a lazy initialiser

4. Should the doc include what it means to return null from a factory method
(presumably not allowed?)


thanks, richard
