Noggit is the world's fastest streaming json parser for java. features:
* fast! measured as the fastest json parser on char[], string input.
* streaming api (stax/pull-parser like) for both easy and efficient parsing
* conforms to the json standard: http://www.ietf.org/rfc/rfc4627.txt
* memory efficiency
* incremental parsing (reader-based) in order to handle huge messages
* a single byte of state needed per nested object or array
* does not read large objects (including primitives) completely
into memory unless asked
* can eliminate most copying, allowing the user to provide
the output buffer for values
* can handle primitives of any size (does not attempt to parse
numerics into a certain language primitives unless asked)
* simple serialization of objects (list, map, etc)
* optional creation of objects (list, map, etc) when parsing.
