Usage: an implementation of this interface is supplied and you must use it as is. You should not reimplement it.
interface CATISAXLocator
Interface for associating a SAX event with a document location.
If a SAX parser provides location information to the SAX application, it does so by implementing this interface and then passing an instance to the application using the document handler's CATISAXDocumentHandler.SetDocumentLocator method. The application can use the object to obtain the location of any other document handler event in the XML source document.
Note that the results returned by the object will be valid only during the scope of each document handler method: the application will receive unpredictable results if it attempts to use the locator at any other time.
SAX parsers are not required to supply a locator, but they are very strong encouraged to do so. If the parser supplies a locator, it must do so before reporting any other document events. If no locator has been set by the time the application receives the CATISAXDocumentHandler.StartDocument event, the application should assume that a locator is not available.
public virtual HRESULT GetColumnNumber( | int& | oNumber) = 0 |
public virtual HRESULT GetLineNumber( | int& | oNumber) = 0 |
public virtual HRESULT GetPublicId( | CATUnicodeString& | oPublicId) = 0 |
This will be the public identifier
public virtual HRESULT GetSystemId( | CATUnicodeString& | oSystemId) = 0 |
If the system identifier is a URL, the parser must resolve it fully before passing it to the application.
