|  | /** | 
|  | * An extension to JSONScreen that performs a Security Check before invoking | 
|  | * doBuildTemplate().  You should extend this class and add the specific | 
|  | * security check needed.  If you have a number of screens that need to perform | 
|  | * the same check, you could make a base screen by extending this class and | 
|  | * implementing the isAuthorized().  Then each screen that needs to perform the | 
|  | * same check could extend your base screen. | 
|  | * | 
|  | * <p>Typically you would extend this class and override the doOutput() method | 
|  | * to use TurbineJsonRpc to register the POJOs that will provide the functions | 
|  | * you are making available via JSON-RPC.  Use JSONScreen if you <b>do not</b> | 
|  | * need the user to be logged in prior to executing the functions you provide.</p> | 
|  | * | 
|  | * <p>Here is an example from a superclass: | 
|  | * <code> | 
|  | * public void doOutput(PipelineData data) throws Exception | 
|  | * { | 
|  | *     User user = data.getUser(); | 
|  | * | 
|  | *     MySecureJsonFunctions myFunctions | 
|  | *             = new MySecureJsonFunctions(user.getName()); | 
|  | * | 
|  | *     // Session specific | 
|  | *     TurbineJsonRpc.registerObject(data.getSession(), "myFunctions", myFunctions); | 
|  | * | 
|  | *     // Global | 
|  | *     //TurbineJsonRpc.registerObjectGlobal("testGlobal", testObject); | 
|  | * | 
|  | *     super.doOutput(data); | 
|  | * } | 
|  | * </code></p> | 
|  | * | 
|  | * <p>The class MyFunctions would be something like: | 
|  | * <code> | 
|  | * public class MySecureJsonFunctions | 
|  | * { | 
|  | *     private final String name; | 
|  | * | 
|  | *     public MySecureJsonFunctions(String name) | 
|  | *     { | 
|  | *         this.name = name; | 
|  | *     } | 
|  | * | 
|  | *     private String getName(String clientParameter) | 
|  | *     { | 
|  | *         return "Client " + clientParameter + " says Hello World to " + name; | 
|  | *     } | 
|  | * } | 
|  | * </code></p> |
