JSON_OBJECT

constant

Constant

string JSON_OBJECT = "\\u{FDD1}";

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:

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}
	}
}

Showing usage to determine if a Value within a Json text is an object:

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.");
		}
	}
}
