Adam Lally resolved UIMA-157.
-----------------------------
Resolution: Won't Fix
Fix Version/s: (was: 2.1)
We did not acheive consensus for this and we will not implement this for 2.1.
I'm closing the issue since we will be starting this discussion from scratch
and may ultimately come up with something completely different.
> 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/[email protected]/msg00945.html
> Proposed sets of methods on each interface:
