virtual void | StartDocument () |
virtual void | StartElement (HtmlElement *element) |
virtual void | EndDocument () |
Note: EndDocument will be called imediately before the last Flush call. | |
virtual void | EndElement (HtmlElement *element) |
virtual void | Flush () |
virtual const char * | Name () const |
The name of this filter -- used for logging and debugging. |
Adds a 'head' element before the 'body', if none was found during parsing. This enables downstream filters to assume that there will be a head.
virtual void net_instaweb::AddHeadFilter::Flush | ( | ) | [virtual] |
Notifies the Filter that a flush is occurring. A filter that's generating streamed output should flush at this time. A filter that's mutating elements can mutate any element seen since the most recent flush; once an element is flushed it is already on the wire to its destination and it's too late to mutate. Flush is initiated by an application calling HttpParse::Flush().
Flush() is called after all other handlers during a HttpParse::Flush().
Reimplemented from net_instaweb::EmptyHtmlFilter.
virtual void net_instaweb::AddHeadFilter::StartDocument | ( | ) | [virtual] |
Starts a new document. Filters should clear their state in this function, as the same Filter instance may be used for multiple HTML documents.
Reimplemented from net_instaweb::EmptyHtmlFilter.
virtual void net_instaweb::AddHeadFilter::StartElement | ( | HtmlElement * | element | ) | [virtual] |
When an HTML element is encountered during parsing, each filter's StartElement method is called. The HtmlElement lives for the entire duration of the document.
Reimplemented from net_instaweb::EmptyHtmlFilter.
