class XMLFilterImpl

File Information

Library: XML
Package: SAX
Header: Poco/SAX/XMLFilterImpl.h

Description

Base class for deriving an XML filter.

This class is designed to sit between an XMLReader and the client application's event handlers. By default, it does nothing but pass requests up to the reader and events on to the handlers unmodified, but subclasses can override specific methods to modify the event stream or the configuration requests as they pass through.

Inheritance

Direct Base Classes: XMLFilter, EntityResolver, DTDHandler, ContentHandler, ErrorHandler

All Base Classes: ContentHandler, DTDHandler, EntityResolver, ErrorHandler, XMLFilter, XMLReader

Known Derived Classes: WhitespaceFilter

Constructors

XMLFilterImpl

XMLFilterImpl();

Construct an empty XML filter, with no parent.

This filter will have no parent: you must assign a parent before you start a parse or do any configuration with setFeature or setProperty, unless you use this as a pure event consumer rather than as an XMLReader.

XMLFilterImpl

XMLFilterImpl(
    XMLReader * pParent
);

Construct an XML filter with the specified parent.

Destructor

~XMLFilterImpl virtual

~XMLFilterImpl();

Destroys the XMLFilterImpl.

parent protected inline

XMLReader * parent() const;

setupParse protected virtual

virtual void setupParse();

Setup the event handlers in the parent reader.
