public abstract class VelocitySecureScreen extends VelocityScreen
VelocitySecureScreen Always performs a Security Check that you've defined before executing the 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.
