J.A.D.E. - specifically RealtimeParser, SAX2-like XML Parser component

[Jon Evans <jo...@misgl.com>]

Hi,

http://jade.dautelle.com/

Java Addition to Default Environment


http://jade.dautelle.com/api/jade/xml/sax/RealtimeParser.html

Anyone seen this?  Don't know if it could be used in Cocoon.  From a 
license point of view its LGPL.

quote:

public final class RealtimeParser
extends java.lang.Object

This class provides a real-time SAX2-like XML parser; this parser is 
/extremely/ fast and *does not create temporary objects* (no garbage 
generated and no GC interruption).

This parser is light (less than 15Kbytes compressed) and maintains a 
very small memory footprint while parsing (e.g. less than 16Kbytes 
while parsing 32Mbytes files). Typical applications include SOAP 
messaging, embedded/realtime systems, web servers (possibly thousands 
instances running concurrently), etc.

Cheers,

Jon

 From JavaDoc:

"In order to avoid String allocation, the SAX2 interface classes had to 
be slightly modified with String being replaced by CharSequence.

Because of these changes RealtimeParser is not SAX2 compliant. If a SAX2 
or a JAXP parser is required, you may consider using the wrapping class 
XMLReaderImpl (fast but allocates temporary String objects)."

Question is, how fast is the XMLReaderImpl? :)
