----------------------------------------------------------------
UIMA-5148 will change the External Resources instantiation to have the creating
ResourceManager be returned from the Reource's getResourceManager() API call.
I think it would be hard to defer the initialization of resources until all the
non-parameterized ones have been loaded (but not initialized).
So, instead, let's address this Jira by the approach in the title - adding an
API that returns a collection of Resource objects that have been registered to
this Resource Manager.

UIMA-5148 will change the External Resources instantiation to have the creating

I think it would be hard to defer the initialization of resources until all the
non-parameterized ones have been loaded (but not initialized).
So, instead, let's address this Jira by the approach in the title - adding an
ability to list External resources being managed by a ResourceManager.
This will add one or two methods to ResourceManager, to return the list of
External Resources. The varieties are needed to handle both:
# ordinary External Resources: these have 1 instance, and are members of the
internal Resource Registration Map.
# parameterized External Resources: these have 0 or more instances, created "on
demand" by the getResource(...) call which passes additional string parameters
to select a particular version of the resource.

> Key: UIMA-2903
> URL: https://issues.apache.org/jira/browse/UIMA-2903
> Project: UIMA
> Issue Type: Improvement
> Components: Core Java Framework, uimaFIT
> Reporter: Richard Eckart de Castilho
> Labels: Resources
> Fix For: 2.3.0uimaFIT
>
>
> uimaFIT currently gets a list of resources that are registered with a
> ResourceManager. This is handled via accessing the "mResourceMap" field of
> the ResourceManager_impl class via reflection. Obviously, this is not a good
> solution.
> uimaFIT iterates over the resources in the context while initializing
> resources that are referenced from other external resources.
> There may be two options:
> # add a listResources() method to the ResourceManager interface
> # get the resources that need to be initialized in some other way. I don't
> know if there is one, because if there was, I'd probably have used it.
> Looking at the @ExternalResource annotations doesn't help, because they do
> not give informations about the resource bindings. The bindings are only
> available in the ResourceManager, which takes us back to 1).
> Would it be possible to add a method allowing to list the resource bindings
> registered in a ResourceManager to the ResourceManager interface?
