Detailed Description

The QSparqlError class provides SPARQL error information.

A QSparqlError object can provide driver-specific error data, including the error message(), number() and type(). The functions all have setters so that you can create and return QSparqlError objects from your own classes, for example from your own SPARQL drivers.
