The current choice in generification doesn't support this; a fix would
be to change AnnotationIndex generification from
public interface AnnotationIndex extends FSIndex<AnnotationFS> to
public interface AnnotationIndex extends FSIndex<AnnotationBaseFS>
Is this correct?
The reason I choose AnnotationFS was that the javadoc says:
"An annotation index provides additional iterator functionality that
applies only to instances of
uima.tcas.Annotation."
The type uima.tcas.Annotation has int begin and end features, which is
represented
as AnnotationFS.
Wouldn't it be a violation to the API if it can also contain non
uima.tcas.Annotation FSes ?
But maybe we should also consider changing the interface to something
like this:
public interface AnnotationIndex<T extends Annotation(Base)FS> extends
FSIndex<T>
