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.

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 requires all field values and array elements to be quoted (e.g. "value"). Unquoted number values are not supported. It would not impact the performance of the parser significantly if support for unquoted numbers were added though.

• 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"] .
