XMLEntityHandler::resolveEntity
virtual InputSource * resolveEntity(XMLResourceIdentifier *resourceIdentifier)=0
This method allows the entity handler to provide customized application specific entity resolution.
XMLEntityHandler::startInputSource
virtual void startInputSource(const InputSource &inputSource)=0
This method will be called before the scanner starts reading from an input source while processing ex...
XMLEntityHandler::expandSystemId
virtual bool expandSystemId(const XMLCh *const systemId, XMLBuffer &toFill)=0
This method allows the passes the scanned systemId to the entity handler, thereby giving it a chance ...
XMLEntityHandler::resetEntities
virtual void resetEntities()=0
This method allows the entity handler to reset itself, so that it can be used again.
XMLEntityHandler::endInputSource
virtual void endInputSource(const InputSource &inputSource)=0
This method get called after the scanner has finished reading from the given input source while proce...
