Adam Lally closed UIMA-157.
---------------------------
won't fix, at least not in this form
> CAS / CasView API refactoring
> -----------------------------
>
> Key: UIMA-157
> URL: https://issues.apache.org/jira/browse/UIMA-157
> Project: UIMA
> Issue Type: Improvement
> Components: Core Java Framework
> Reporter: Adam Lally
> Assigned To: Adam Lally
>
> 1. Goals
> The following are confusing (or some might say, "broken")
> (a) the interface "CAS" can be an interface to either the whole CAS or to a
> view. Methods like this are poor:
> CAS view = cas.getView(name);
> (b) the logic determining which "CAS" (a view or the whole CAS) gets
> passed to an
> annotator's process method is needlessly complicated.
> We would like to improve this in v2.1, so we have a short runway to implement
> it. It's acceptable if what we do breaks multi-view
> annotators/applicatoins, but it cannot break single-view
> annotators/applications.
> We want whatever we do to be easier to document and explain to users
> than what we currently have.
> 2. Proposed Solution
> We don't plan to change the fundamental design of views at this point
> - there isn't time and it's too controversial. A view still consists
> of an index repository and a Sofa. (Yes, I know someday a view may
> not have a Sofa - but for now, it does.)
> A. New CasView interface
> We create a new interface CasView. All of the CAS.getView() methods
> will now return type CasView (instead of CAS).
> The CasView interface will contain all of the sofa-access methods and
> indexing-related methods that are on the CAS interface.
> Further discussion:
> http://www.mail-archive.com/uima-dev@incubator.apache.org/msg00945.html
> Proposed sets of methods on each interface:
