Richard Eckart de Castilho updated UIMA-5067:
---------------------------------------------
Description:
The returned object of JCasUtil.selectSingleRelative() should match the
generic-type of its first argument.
However, when the last argument is 0, it returns an object whose class is
identical to the second argument's class.
{noformat}
for (Annotation aa : cas.getAnnotationIndex(AA.type))
{
Object ab = JCasUtil.selectSingleRelative(AB.class, aa, 0);
System.out.println(ab.getClass().getName());
}
{noformat}
The output ought to be "AB", however it is "AA".
(When the last argument is 0, I thought it would find an annotation which
begins exactly where the annotation of the second argument begins. However, it
returns a wrong object).
Perhaps, if last-argument 0 is prohibited, an exception should be thrown (and
documented).
Thanks.
