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 JSON standard: http://www.ietf.org/rfc/rfc4627.txt
• Conforms to JSON standard: http://rfc7159.net/rfc7159
• Memory efficiency:
  • Incremental parsing (Reader-based) in order to handle huge messages.
  • A single byte of state needed per nested object or array.
  • Doesn't read large objects (including primitives) into memory unless asked.
  • Can eliminate most copying, allowing user to provide value output buffers.
• Can handle primitives of any size (does not attempt to parse numerics into a certain language primitive unless asked).
• Simple serialization of objects (List, Map, etc).
• Optional creation of objects (List, Map, etc) when parsing.

Syntax Features (Optional):

• Single-line comments using either # or //
• Multi-line comments using C style /* comments in here */
• Single quoted strings.
• Unquoted object keys. Example: {answer : 42}
• Unquoted string values. Example: {first: Yonik, last: Seeley}
• Allow backslash escaping of any character.
• Allow trailing commas and extra commas. Example: [9,4,3,]
• Handle nbsp (non-break space, \u00a0) as whitespace.
• Optional opening and closing brackets. "a" :"Val1", "b" : "Val2" is equivalent to {"a" :"Val1", "b" : "Val2" }
• Optional comma between objects {"a" :{"b:"c"} "d": {"e":"f"}} or [{"a":"b"}{"c":"d"}] are all valid
• Optional colon between key and value {"a" {"c":"d"}} and {"a" ["b","c"]} are valid
