Annotation Type Before

@Target(METHOD)
@Retention(RUNTIME)
public @interface Before

Marks a method as a 'Before' handler for Web Script requests.

Before handlers accept the same types of parameters as Attribute and Uri handlers. They can return a boolean to indicate control flow in the overall request handling cycle.

 @Before
 public boolean checkIfNodeExists(@RequestParam NodeRef nodeRef, WebScriptResponse response) {
        if (nodeService.exists(nodeRef)) {
                return true; // Proceed.
        } else {
                response.setStatus(404);
                return false; // End request handling.
        }
 }
 

Like Attribute handlers, the order in which Before handlers are invoked is undefined. You should avoid logical dependencies between Before handlers.
