Yes, you can access the ResultConfig objects before the Action executes, and you can access the final Result object using a PreResultListener.

## Accessing the ResultConfig Objects

If you need to work with the set of ResultConfigs before the Action executes, you can use an Interceptor to process the Map returned by `getResults`.

    public class MyInterceptor implements Interceptor {
      // ...
      public String intercept(ActionInvocation invocation) throws Exception {
        Map resultsMap = invocation.getProxy().getConfig().getResults();

          // do something with ResultConfig in map

        return invocation.invoke();
      }
      // ...
    }

If you are writing against Java 5, you could use a generic when obtain the map.

    Map<String, ResultConfig> resultsMap = invocation.getProxy().getConfig().getResults();

## Adding a PreResultListener

If you need to work with the final Result object before it is executed, you can use an Interceptor to register a PreResultListener. The code example creates a PreResultListener as an anonymous inner class.

    public class MyInterceptor implements Interceptor {
      // ...
      public String intercept(ActionInvocation invocation) throws Exception {

        invocation.addPreResultListener(new PreResultListener() {

          public void beforeResult(ActionInvocation invocation, String resultCode) {
            Map resultsMap = invocation.getProxy().getConfig().getResults();
            ResultConfig finalResultConfig = resultsMap.get(resultCode);

              // do something interesting with the 'to-be' executed result

            }

          });

        return invocation.invoke();
      }
      // ...
    }

If you are writing against Java 5, you could use a generic when obtain the map.

    Map<String, ResultConfig> resultsMap = invocation.getProxy().getConfig().getResults();
