Burn Lewis commented on UIMA-5043:
----------------------------------
The default set of external overrides is loaded from the files specified by the
system property 'UimaExternalOverrides' but an analysis engine can be created
with a different set of overrides by passing ia Settings object in the
additional-parameters argument for the produceAnalysisEngine method. These
settings may override configuration parameters in this AE and now will also be
accessible via the 2 new UimaContext methods described above.
But in some applications non-UIMA code needs access to a common set of
configuration parameters and the default set of external overrides is a good
candidate, so we could add a static method to the UimaFramework class to allow
non-UIMA code to share these configuration values.
e.g. String paramValue =
UimaFramework.getDefaultExternalOverrides().getExternalOverride(paramName);
This will also ensure that the framework will share a single copy of the
default settings amongst all engines that use them.

> 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)
