com.hp.hpl.jena.sparql.lang.SPARQLParser
This class provides the root of lower level access to all the parsers. Each subclass hides the details of the per-language exception handlers and other javacc details to provide a methods that deal with setting up Query objects and using QueryException exceptions for problems.
