[jira] Created: (UIMA-1208) How to get the element type of a
uima.cas.FSList feature
How to get the element type of a uima.cas.FSList feature
--------------------------------------------------------
Key: UIMA-1208
URL: https://issues.apache.org/jira/browse/UIMA-1208
Project: UIMA
Issue Type: Bug
Components: Core Java Framework
Affects Versions: 2.2.2
Environment: Fedora 9
Reporter: Manuel Fiorelli
Priority: Minor
The documentation
http://incubator.apache.org/uima/downloads/releaseDocs/2.2.2-incubating/docs/html/references/references.html#ugr.ref.xml.component_descriptor.type_system.features
states that in the type system descriptor one may use <elementType> to constraint the type of elements in both array and list features.
However, if one gets the type system of a CAS [myCas.getTypeSystem()],
1) if the feature range is an array, he can retrieve the element type through the method Type.getComponentType()
2) if the feature range is a list, there seems not to be any way to get the element type, since the method Type.getComponentType() returns null

Marshall Schor commented on UIMA-1208:
--------------------------------------
The element-type for an FsList is used for "documentation purposes" and it's used in the Ecore type system conversion stuff. It is not currently used by much else.
However, it would be good if the element type is accessible via the Type system. I'll look into whether this can be done, and make the update, unless there are objections.

--------------------------------------
After looking into this, it appears quite complex to implement. So, for now, I will just update the documentation. Others may wish to contribute a patch :-).
