Burn Lewis commented on UIMA-5043:
----------------------------------
I've tried putting the functions on UIMAFramework (since the other choices were
interfaces) and do feel uncomfortable with the number of changes. I like
Richard's suggestion of exposing a single method to get the context as I can
then put the access methods on UimaContext where they can be directly used by
annotators, leaving the thread-local approach only necessary for POJOs, e.g.
String value = aContext.getSetting(paramName); // For annotators
String value = UimaContextHolder.getContext().getSetting(paramName); // For
POJOs
I'd prefer not to expose the Settings_impl object as I don't want to make it
easy for users to modify it.
As to the initialization from system properties, the applications that use
UIMA-AS and DUCC provide a descriptor and a few system properties for
configuration, e.g. framework_impl, logging-properties, datapath,
external-overrides. A case could be made that only the first of these MUST be
global, but currently only the last can be made AE dependent. We could add
some new attribute to an AE descriptor to specify the settings files but that
might make it too easy to accidentally specify different settings on nested AEs.

> URL: https://issues.apache.org/jira/browse/UIMA-5043
> Project: UIMA
> Issue Type: Improvement
> Components: Core Java Framework
> Reporter: Burn Lewis
> Assignee: Burn Lewis
> Priority: Minor
> Fix For: 2.9.0SDK
>
>
> The framework loads the external override settings and uses them in any
> configuration parameter that has an external override name attached, Users
> have asked for the ability to access these values directly without the
> indirection of configuration parameter entries in descriptors. Currently the
> complete Settings object that holds all the external override settings loaded
> by the framework is accessible via UimaContextAdmin.
> An improvement would be to allow individual values to be read using a method
> in the UimaContext interface, perhaps:
> String getExternalOverride(String name)
> String[] getExternalOverrideArray{String name)
