Description

Constant: string JSON_OBJECT = "﷑";

The string constant JSON_OBJECT has the value "﷑"

Used with the llList2Json function to indicate that the list provided is a strided list of "Key", Value pairs (which may be empty), and that a string representing a Json object will be returned.

Also a possible return value for the llJsonValueType function that indicates the Json data type of at the specifier location within a given Json text is, in fact, a JSON_OBJECT.

Examples

Showing use to form a Json object: <lsl>string jsonText;

default { state_entry() { // NOTE: All even numbered elements in the supplied list MUST be strings or JSON_INVALID will be returned! jsonText = llList2Json(JSON_OBJECT, ["A", 3, "B", <1.0,1.0,1.0>, "C", "A phrase", "D", PI]); } touch_start(integer total_number) { // In the resulting Json object, "Keys" are separarted from Values by a colon (:) // and "Key":Value pairs by a comma (,). llOwnerSay(jsonText); // {"A":3,"B":"<1.000000, 1.000000, 1.000000>","C":"A phrase","D":3.141593} } }</lsl>

Showing usage to determine if a Value within a Json text is an object: <lsl>string jsonText;

default { state_entry() { // Set jsonText to [3,{"A":77,"B":66},"A phrase"] // A Json array whose second element is a Json object jsonText = "[3,{\"A\":77,\"B\":66},\"A phrase\"]"; llOwnerSay(jsonText); } touch_start(integer total_number) { // Test the entirety of the Json text to see if it's an object // Note use of the empty list for this if (llJsonValueType(jsonText, []) == JSON_OBJECT) { llOwnerSay("The supplied string is a Json object."); } else { llOwnerSay("The supplied string is not a Json object."); // TRUE }

// Test second element of the array if (llJsonValueType(jsonText, [1]) == JSON_OBJECT) { llOwnerSay("The second element of the array is a Json object."); // TRUE } else { llOwnerSay("The second element of the array is not a Json object."); } } }</lsl>
