How to implement CAF Receiver Queueing

I'm confused by this page https://developers.google.com/cast/docs/caf_receiver_features#queueing

It seems to assume that any implementation of 'YourServer' will return synchronous results rather than promises or observables.

Does anyone have a working example where the queue is managed by an http based service?

Edit:

I've found one major problem with this page. It inconsistently names the cast.framework.QueueBase base class. In some places it correctly names it cast.framework.QueueBase while in others it names it cast.framework.messages.QueueBase. In particular, the link to the class documentation uses the wrong name. The correct link is to https://developers.google.com/cast/docs/reference/caf_receiver/cast.framework.QueueBase.

This helps a lot since it says fetchItems and its siblings return:

"(non-null Array of non-null cast.framework.messages.QueueItem or non-null Promise containing non-null Array of non-null cast.framework.messages.QueueItem)".

Solution

  • OK, there were bugs in the documentation. I reported these on the Google+ community and they are now fixed.

    I've got a sample queueing receiver working and made a gist of it.
