Minto van der Sluis reassigned CLEREZZA-782:
--------------------------------------------
Assignee: Minto van der Sluis
> Add meta data (varNames) to Sparql ResultSet
> --------------------------------------------
>
> Key: CLEREZZA-782
> URL: https://issues.apache.org/jira/browse/CLEREZZA-782
> Project: Clerezza
> Issue Type: Bug
> Components: rdf.core
> Reporter: Minto van der Sluis
> Assignee: Minto van der Sluis
>
> The class ResultSet only allows indirect access to the varNames in the query
> results. There are a number of drawbacks to the current solution:
> 1) the iterator needs to be accessed to get the varNames from
> SolutionMapping.getKeySet()
> 2) I suspect that optional varNames present in the Query but not in the
> resultset data will not appear in SolutionMapping.getKeySet()
> 3) If the RestultSet is empty there is no way to determine the varNames();
> Both Jena and Sesame support retrieving the varNames from the ResultSet.
