public interface AlwaysPipe<D,F,D_OUT,F_OUT,P>

A pipe invoked when the Promise's state becomes Promise.State.RESOLVED or Promise.State.REJECTED. Pipes allow to start a new Deferred and any state change or update invoked on the new Deferred is piped to the outer Promise. This allows to chain asynchronous calls or convert a rejection into resolve or vice versa.
