Detailed Description

This abstract class defines a callback mechanism for the scanner.

By creating a class that implements this interface and plugging an instance of that class into the scanner, the scanner will call back on the object's virtual methods to report error events. This class is also used with the validator, to allow it to report errors.

This class is primarily for use by those writing their own parser classes. If you use the standard parser classes, DOMParser and SAXParser, you won't use this API. You will instead use a similar mechanism defined by the SAX API, called ErrorHandler.

pure virtual

Called to report errors from the scanner or validator.

This method is called back on by the scanner or validator (or any other internal parser component which might need to report an error in the future.) It contains all the information that the client code might need to report or log the error.

Parameters

errCode	The error code of the error being reported. What this means is dependent on the domain it is from.
errDomain	The domain from which the error occured. The domain is a means of providing a hierarchical layering to the error system, so that a single set of error id numbers don't have to be split up.
type	The error type, which is defined mostly by XML which categorizes errors into warning, errors and validity constraints.
errorText	The actual text of the error. This is translatable, so can possibly be in the local language if a translation has been provided.
systemId	The system id of the entity where the error occured, fully qualified.
publicId	The optional public id of the entity were the error occured. It can be an empty string if non was provided.
lineNum	The line number within the source XML of the error.
colNum	The column number within the source XML of the error. Because of the parsing style, this is usually just after the actual offending text.

Implemented in SAXParser, and XercesDOMParser.

◆ resetErrors()

virtual void XMLErrorReporter::resetErrors ( )

pure virtual

Called before a new parse event to allow the handler to reset.

This method is called by the scanner before a new parse event is about to start. It gives the error handler a chance to reset its internal state.
