Marshall Schor commented on UIMA-5043:
--------------------------------------
UIMA applications are pipelines having a UIMA context (some of which might be
shared).
1 or more UIMA applications can be run in one JVM, under the same class loader;
each one could have their own UIMA extension class loader for loading
user-provided things (resources, annotator class, and JCas classes).
1 or more sets of UIMA applications can be run in one JVM using separate class
loaders (think of a Web App server, running UIMA in servlets, each with an
isolated classpath.
The two ways of specifying external overrides ( 1) via
-DUimaExternalOverrides, or 2) as a parameter in the additional-parameters
argument for the produceAnalysisEngine method) provide a way to specify a
not-global or a completely global version of this.
The proposed API only addresses the completely global version; it would seem
that non-UIMA code wanting access could easily be associated with a particular
pipeline, and want to pick up the associated configuration for that pipeline,
not a completely global one.
Maybe we could find a way to accomodate that?

> Key: UIMA-5043
> 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)
