Subject [jira] Created: (GRFT-101) Allow developer to supply "newInstace" method in subclass of ObjectConverterImpl

Allow developer to supply "newInstace" method in subclass of ObjectConverterImpl
--------------------------------------------------------------------------------

                 Key: GRFT-101
                 URL: http://issues.apache.org/jira/browse/GRFT-101
             Project: Graffito
          Issue Type: Improvement
    Affects Versions: 1.0-a1-dev
         Environment: JCR Mapping
            Reporter: Dan Connelly


I used a simple change in ObjectConverterImpl.   This allows me to use a Factory class (in
place of JavaBean constructors) in my object model.

I added the following method to ObjectConverterImpl.:

   protected Object newInstance(String className) {
       return ReflectionUtils.newInstance(className);
   }


Elsewhere in ObjectConverterImpl, it will now invoke

           this.newInstance(classDescriptor.getClassName());

every where that is previously invoked

           ReflectionUtils.newInstance(classDescriptor.getClassName());

Now I can over-ride the newInstance method in MyObjectConverterImpl (which subclasses ObjectConverterImpl).
  This allows me to construct objects for my model using its Factory class.
