enumerate deprecated, Use `.enumerator` from Play Iteratee modules

[Alexandre Russel]

Hi,

 could someone show  (including import and libraries) how to migrate the deprecated code:

cursor.enumerate

Unit test and documentation are still showing it, but it is marked as deprecated with the message: "Use `.enumerator` from Play Iteratee modules"

Thanks,

Alex

Hi,

The iteratee support is being moved to a separate module.
You can see examples of how to use it in the tests of this module.

The tests link is broken. Meanwhile, CursorSpec contains tests for methods that are all deprecated (all the enumerate* methods). Can you provide a sample or at least point me to the tests that demonstrate how to stream cursors now?

Thanks.

Well, I do see the foldResponses and foldResponsesM, but it isn't clear how they work and what the differences are. Any guidance is appreciated.

- The `.foldX` are provided for a custom streaming, and documented in the API reference: http://reactivemongo.org/releases/0.11/api/index.html#reactivemongo.api.Cursor@foldWhile[A](z:=%3EA,maxDocs:Int)(suc:(A,T)=%3Ereactivemongo.api.Cursor.State[A],err:reactivemongo.api.Cursor.ErrorHandler[A])(implicitctx:scala.concurrent.ExecutionContext):scala.concurrent.Future[A]
- The previous CursorSpec should obviously go on testing the deprecated enumerate function to ensure the backward compatibility.
- As indicated in the deprecation message, the iteratee support is being moved as a separate module, so that's where the up-to-date tests and example can be found: https://github.com/ReactiveMongo/ReactiveMongo-Streaming/blob/master/iteratees/src/test/scala/CursorSpec.scala

This information is very helpful. Thanks.
