Subject [Vote] POJOfied Environment
Date Thu, 12 May 2005 14:48:24 GMT
To simplify and make the environment handling in flow, jxtg, modules and 
possibly other places more coherent, I propose that we extend the Cocoon 
environment apis with some utility methods that makes the environment 
more reflection friendly. See for motivation, 
discussion and technical issues.

More specifically I propose is that we extend o.a.c.environment.Request 

  Map getAttributes();
  Map getParameters();
  Map getHeaders();

and o.a.c.environment.Session and o.a.c.environment.Context with:

  Map getAttributes();

The utility methods will be implemented in terms of current environment 
methods in abstract base classes, so for the various environments in 
Cocoon core and blocks the only difference will be that they will extend 
the abstract base classes instead of implementing the interfaces directly.

As Java faces use getAttributeMap() etc and servlet 2.4 has the method 
getParameterMap() in ServletRequest, we could consider using such name 
convention instead. But that leads to "request.parameterMap.blah" 
instead of "request.parameters.blah" which is different from our current 
use and in Sylvain's and my opinion looks ugly.

Please cast your votes:

[ ] Go ahead and implement the environment extensions proposed above.
[ ] Implement the environment extensions but use the *Map() syntax instead.
[ ] Don't extend the environment.
