This repository contains a simple JSON parser as a proof-of-concept of how to implement high performance parsers in Java, using index overlay parser design, as described here:

http://www.infoq.com/articles/HIgh-Performance-Parsers-in-Java-V2

The parser is only at a proof-of-concept quality level, so it is not recommended that you use it for production. The purpose of the parser is to allow the user to study its design, not to plug it into your apps.

Known issues:

• The parser does not care if you have a comma or not between fields or elements in an array. It will accept ["value1" "value2"] as well as ["value1", "value2"] . Enforcing comma separators would not impact performance significantly.
