The magic happens in SPARQL_Query#sendResults(HttpAction action,
SPARQLResult result, Prologue qPrologue)
...
if ( result.isResultSet() )
ResponseResultSet.doResponseResultSet(action,
result.getResultSet(), qPrologue) ;
which eventually leads me to
94: ResponseResultSet#doResponseResultSet$(HttpAction action, ResultSet
resultSet, Boolean booleanResult, Prologue qPrologue)
...
blah blah blah
...
if ( equal(serializationType, WebContent.contentTypeResultsXML) )
sparqlXMLOutput(action, contentType, resultSet, stylesheetURL,
booleanResult) ;
else if ( equal(serializationType,
WebContent.contentTypeResultsJSON) )
jsonOutput(action, contentType, resultSet, booleanResult) ;
else if ( equal(serializationType, WebContent.contentTypeTextPlain)
)
textOutput(action, contentType, resultSet, qPrologue,
booleanResult) ;
else if ( equal(serializationType, WebContent.contentTypeTextCSV) )
csvOutput(action, contentType, resultSet, booleanResult) ;
else if (equal(serializationType, WebContent.contentTypeTextTSV) )
tsvOutput(action, contentType, resultSet, booleanResult) ;
else
errorBadRequest("Can't determine output serialization:
"+serializationType) ;
Right now I'm putting my bets on the resultSet above... which is
subsequently ServletOutputStream object being the golden snitch I am
looking for. It feeds down until I eventually I find
ServletOutputStream out = action.response.getOutputStream() ;
I am hoping that this out object is the one I am after.
It would be nice if it was :0)
