Annotation Type ChangeSet

@Target(value=METHOD)
 @Retention(value=RUNTIME)
public @interface ChangeSet

The ChangeSet annotation attached to a public method specifies that the method implements the ChangeSet in a Batch request.

A method to which this annotation is attached must provide the following:

1. Input parameter of type ChangeSetHandler

The following sample code shows how you can apply this annotation to a method:

 @ChangeSet (serviceName = "EPMSampleService")
 public void processChangeSet(ChangeSetHandler changeSetHandler) {
        try {
                //Add your initialization logic to save the current state of data
                //...

                //Iterate over the data modification operations in the ChangeSet
                while (changeSetHandler.hasNextRequest()) {
                        //Retrieve the request, process it and add the response for each operation
                        Request request = changeSetHandler.nextRequest();
                        Response response = changeSetHandler.handleRequest(request);
                        changeSetHandler.addResponse(response);
                }
                //Add your logic to commit the changes
                //...
   } catch (Exception e) {
        //Add your logic to rollback the changes
                //...
   }
 }
 

By applying the ChangeSet annotation, the processChangeSet method gets invoked whenever there is a batch request with ChangeSet on EPMSampleService.
