Description
Constant: string JSON_ARRAY = "";The string constant JSON_ARRAY has the value ""
Used with the llList2Json function to indicate that the provided list (which may be empty) is to be used to encode and return a string serialization of a Json array.
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 array.

Examples
Showing usage to form a Json array:
string jsonText;
default
{
state_entry()
{
jsonText = llList2Json(JSON_ARRAY, ["A", 3, "B", <1.0,1.0,1.0>, "C", "A phrase", "D", PI]);
}
touch_start(integer total_number)
{
// In the resulting Json array, all Values are separated 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 array:
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 array
// Note use of the empty list for this
if (llJsonValueType(jsonText, []) == JSON_ARRAY)
{
llOwnerSay("The supplied string is a Json array."); // TRUE
} else {
llOwnerSay("The supplied string is not a Json array.");
}
// Test second element of the array
if (llJsonValueType(jsonText, [1]) == JSON_ARRAY)
{
llOwnerSay("The second element of the array is a Json array.");
} else {
llOwnerSay("The second element of the array is not a Json array."); // TRUE
}
}
