Richard Eckart de Castilho commented on UIMA-3597:
--------------------------------------------------
Has been implemented for cases where uimaFIT (SimplePipeline / JCasIterable) is
instantiating both, reader and AEs at the same time. Has not been implemented
for cases where uimaFIT already receives externally instantiated readers or
AEs. In the latter case, the caller is responsible for instantiating them with
a common resource manager.
> CollectionReader and Annotators not having access to the same
> ExternalResource instance

> Key: UIMA-3597
> URL: https://issues.apache.org/jira/browse/UIMA-3597
> Project: UIMA
> Issue Type: Bug
> Components: uimaFIT
> Affects Versions: 2.0.0uimaFIT
> Reporter: Swirl
> Assignee: Richard Eckart de Castilho
> Priority: Minor
> Fix For: 2.0.1uimaFIT
>
>
> Creating a pipeline as follows:
> a. CollectionReader
> b. AnnotatorA
> c. AnnotatorB
> All the above (including the CollectionReader and the 2 annotators) have a
> dependency on an ExternalResource.
> Here's a shortened code that I used:
> // create the external resource desc
> ExternalResourceDescription myExternalResourceDesc =
> createExternalResourceDescription();
> // create the CollectionReaderDescription, with the external resource desc
> CollectionReaderDescription myCollectionReaderDesc =
> createDescription(myExternalResourceDesc);
> // create the MyAnnotatorA desc, with the external resource desc
> AnalysisEngineDescription myAnnotatorADesc =
> createPrimitiveDescription(myExternalResourceDesc);
> // create the MyAnnotatorB desc, with the external resource desc
> AnalysisEngineDescription myAnnotatorBDesc =
> createPrimitiveDescription(myExternalResourceDesc);
> // run
> SimplePipeline.runPipeline(myCollectionReaderDesc, myAnnotatorADesc,
>
> myAnnotatorBDesc);
> In the initialize(UimaContext context) method of collection reader and
> annotator, I print out the instance of the ExternalResource:
> MyCollectionReader:com.example.MyExternalResource <at> 26a7dd39
> MyAnnotatorA:com.example.MyExternalResource <at> 6ee1dac2
> MyAnnotatorB:com.example.MyExternalResource <at> 6ee1dac2
> As you can see, MyAnnotatorA and MyAnnotatorB got the same instance of the
> ExternalResource, but MyCollectionReader got a different instance.
> They should be accessing the same ExternalResource instance.
