public static interface Stage.TakeWhile extends Stage
A take while stage.The given
predicate
must be invoked on each element consumed. While the predicate returnstrue
, the element must be emitted, when the predicate returnsfalse
, the element must not be emitted, downstream must be completed and upstream must be cancelled.The
predicate
must not be invoked again once it returnsfalse
for the first time. Any elements supplied by upstream before it handles the cancellation signal must be dropped.Any
RuntimeException
thrown by the predicate must be propagated downstream as an error, and upstream must be cancelled. Any subsequent elements received from upstream before the cancellation signal is handled must be dropped.
