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.
Also a return value for llJsonGetValue to signify a specifier list attempting to access a nonexistent location within a Json text (see Examples).
Caveats
- Do not use JSON_INVALID with the llList2Json or llJsonSetValue functions. Otherwise noncompliant, invalid Json text will result.
