method fromJSON

This method populates the array from a JSON UTF-8 encoding such as what was returned from toJSON. The JSON string must start with "[" and end with "]". All values are removed from the array first.

var arrayObj = shell.serviceManager.basics.array;
arrayObj.addValue(42);
arrayObj.addValue("Hello World");

var users = shell.serviceManager.basics.array;
var keyPair = shell.serviceManager.basics.dictionary;

users.addValue("john");
users.addValue("tom");

keyPair.setValueForKey(users, "brother");

arrayObj.addValue(users);
arrayObj.addValue(keyPair);
arrayObj.addValue(false);

var jsonStream = shell.serviceManager.basics.memoryStream;
arrayObj.toJSON(jsonStream);

/*
The resulting JSON in the stream will look like this:
[
    42,
    "Hello World",
    ["john", "tom",]
    {"brother":["john", "tom"]},
    "false"
]
*/

var arrayObj2 = shell.serviceManager.basics.array;
arrayObj2.fromJSON(jsonStream);
jsonStream.close();
/*fromJSON will remove all the elements first
The resulting arrayObj2 will look like this:
42
"Hello World"
Basics::array Object
    "john"
    "tom"
Basics::dictionary Object
    "brother"    Basics::array Object
                    "john"
                    "tom"
