private constructors for generated classes

[christian.humer at gmail.com]

Hi,

There is no way to make the node constructors public with an annotation. 
For quick experiments I usually copy the generated code and alter it or 
directly or you can modify the generator code. You can alter 
NodeFactoryFactory#createFactoryMethods and modify the line:

ElementUtils.setVisibility(constructor.getModifiers(), 
Modifier.PRIVATE);
to
ElementUtils.setVisibility(constructor.getModifiers(), Modifier.PUBLIC);
to make the node constructors visible.

Happy experimenting.
