Adam Lally commented on UIMA-116:
---------------------------------

Update:

There is related discussion currently onging about refactoring the CAS 
interface and in the process creating a new CasView interface.

Also, the plan is to support single-view components without requiring any code 
change.  This would be done by deprecating but not removing the view-related 
(sofa and index access) methods on the CAS interface, and having them 
auotmatically forward to the "current" view.

> Always deliver the base CAS to the process method

> Currently there is a distinction made for "single view" and "multiple view" 
> components. The UIMA architecture standard proposes that all components are 
> multiple view components and be delivered a handle to the base CAS, and the 
> component retrieves views as required. The change to existing "single view" 
> component would be to add one line of code in the process method: cas = 
> passInCas.getView(), which would return the View currently given to these 
> components as determined by Sofa mapping.
