Gerrick; Here's an example of a callback that will print out the
results of a query:
function selectCallback(g:Graph,sparql:String,results:Array):void
{ for each (var result:Dictionary in results)
{ trace(“result:”);
for (var key:String in result)
{ trace(“\t” + key + “: “ +
result[key]);
}
}
}
So, given the following query, each result in the results parameter to
the callback is a Dictionary containing keys 'subject' and 'object'
per the variable bindings in the query.
SELECT ?subject ?object
WHERE {
?subject rdf:type ?object .
}
