DeterministicJsFilter (RewriteDriver *driver) | |
virtual void | StartDocument () |
virtual void | StartElement (HtmlElement *element) |
virtual const char * | Name () const |
The name of this filter -- used for logging and debugging. |
Injects javascript at the beginning of the head tag to make it deterministic. The JS redefines functions like Math.random and Date. This filter is useful for testing and measurement but does not provide any latency gains. A head element is added if it is not already present in the html.
virtual void net_instaweb::DeterministicJsFilter::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::DeterministicJsFilter::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.
