interface CATISAXXMLFilter
Interface for an XML filter.
An XML filter is like an XML reader, except that it obtains its events from another XML reader rather than a primary source like an XML document or database. Filters can modify a stream of events as they pass on to the final application.
The CATSAXDefaultXMLFilter helper class provides a convenient base for creating SAX2 filters, by passing on all CATISAXEntityResolver, CATISAXDTDHandler, CATISAXContentHandler and CATISAXErrorHandler events automatically.
public virtual HRESULT GetParent( | CATISAXXMLReader_var& | oParent) = 0 |
This method allows the application to query the parent reader (which may be another filter). It is generally a bad idea to perform any operations on the parent reader directly: they should all pass through this filter.
public virtual HRESULT SetParent( | const CATISAXXMLReader_var& | iParent) = 0 |
This method allows the application to link the filter to a parent reader (which may be another filter). The argument may not be NULL_var.
