----------------------------------
Summary: Purpose of EvaluatorSimple and OpExecutor
Key: JENA-2020
URL: https://issues.apache.org/jira/browse/JENA-2020
Project: Apache Jena
Issue Type: Question
Components: ARQ
Reporter: Martin Pekár
I am in the midst of adding a new operator in the transformation of OpBGP. I am
now trying to implement the execution of the operator in the query plan, but I
am now slightly confused about the purpose of EvaluatorSimple used in
EvaluatorDispatch and OpExecutor. At the moment, it seems like they are doing
the same thing. The difference seems to be that OpExecutor stores the result of
applying the operator in a QueryIterator, whereas EvauatorSimple stores its
result in a Table.
Can someone give me an explanation of purposes of these two classes and how
they should be used?
