Lifecycle Hooks

Lifecycle hooks allow you to hook into lifecycle events of the servlet/resource creation and REST calls.

@Rest(...) public class MyResource { // Our database. private Map<Integer,Object> myDatabase; @RestHook(INIT) public void initMyDatabase(RestContextBuilder builder) throws Exception { myDatabase = new LinkedHashMap<>(); } }

Or if you want to intercept REST calls:

@Rest(...) public class MyResource { // Add a request attribute to all incoming requests. @RestHook(PRE_CALL) public void onPreCall(RestRequest req) { req.setAttribute("foo", "bar"); } }

The hook events can be broken down into two categories:
