Description
Constant: string JSON_INVALID = "";The string constant JSON_INVALID has the value ""
A return value that indicates an invalid 'type' was specified to the llList2Json function.
Also a return value for llJsonValueType function indicating the data type of a given address specifier in a given string-serialized JSON object.
