It is sometimes more convenient and less ambiguous to have a NULL object than to use Java's null value.

Usage

From source file:sh.calaba.driver.client.model.impl.RemoteObject.java

protected Object get(WebDriverLikeCommand command, JSONObject payload) {
    Path p = new Path(command).withSession(getSessionId());

    WebDriverLikeRequest request = new WebDriverLikeRequest(command.method(), p, payload);

/**
 * Given an object extracted from JSONObject field, convert it to an
 * appropriate object with type appropriate for given type so that it can be
 * assigned to the associated field of the ummarshalled object. eg.
 * JSONObject value from a JSONObject field probably needs to be
 * unmarshalled to a class instance. Double from JSONObject may need to be
 * converted to Float. etc./*www  .  j a v  a 2  s.  c om*/
 *
 * @param val Value extracted from JSONObject field.
 * @param genericType Type to convert to. Must be generic type. ie. From
