Example

// Given a JSON message like:
message = qie.createJSONMessage(
    JSON.stringify(
        {
            "name": "David",
            "age": 41,
            "favorite movie": {
                "title": "JAWS",
                "release-date": 1978
            },
            "children": []
        }
    )
);

// Check whether a node is a JSON object
if (message.isJSONObject("/favorite movie")) {
    // The favorite movie node is an object, so it has child nodes of its own.
}

if (!message.isJSONObject("/age")) {
    // The age node is a scalar value, not an object.
}
