Detailed Description

This abstract class is a callback mechanism for the scanner.

By creating a derivative of this class and plugging into the scanner, the scanner will call back on the object's methods to entity events.

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 EntityResolver.

Protected default constructor.


Member Function Documentation

void XMLEntityHandler::endInputSource ( const InputSource & inputSource ) [pure virtual]
 

This method get called after the scanner has finished reading from the given input source while processing external entity references.

Parameters:
inputSource   The input source for the entity

Reimplemented in DOMParser, and SAXParser.

bool XMLEntityHandler::expandSystemId ( const XMLCh * const,
XMLBuffer & toFill ) [pure virtual]
 

This method allows the passes the scanned systemId to the entity handler, thereby giving it a chance to provide any customized handling like resolving relative path names.

The scanner first calls this method before calling resolveEntity.

Parameters:
systemId   The system id extracted by the scanner from the input source.
toFill   The buffer in which the fully expanded system id needs to be stored.

Reimplemented in DOMParser, and SAXParser.

void XMLEntityHandler::resetEntities ( ) [pure virtual]
 

This method allows the entity handler to reset itself, so that it can be used again.

It is called prior to a new document parse operation.

Reimplemented in DOMParser, and SAXParser.

InputSource * XMLEntityHandler::resolveEntity ( const XMLCh *const publicId,
const XMLCh *const systemId ) [pure virtual]
 

This method allows the entity handler to provide customized application specific entity resolution.

This method is defined by SAX 1.0 API.

Parameters:
systemId   The system id of the external entity reference.
publicId   The public id of the external entity reference.

Reimplemented in DOMParser, and SAXParser.

void XMLEntityHandler::startInputSource ( const InputSource & inputSource ) [pure virtual]
 

This method will be called before the scanner starts reading from an input source while processing external entity references.

Parameters:
inputSource   The external input source.

Reimplemented in DOMParser, and SAXParser.
