Exactly, it's a sort of a queue.

Each time a task finishes, it invokes the normal onSuccess method, which in 
turn invokes the 
onSuccessImpl (where you would now put your logic). Once onSuccessImpl is 
complete, the next async 
call to the server is invoked.

Each call can be "daisy-chained" onto the previous one, it's basically just a 
linked-list of async 
invocations, and their return logic (in this case with a generic onFailure 
method thrown in for 
easier coding).

Hope it helps,
