Method Detail
-
request
void request​(long n)
Deprecated.No operation will be sent to MongoDB from theObservable
until demand is signaled via this method.It can be called however often and whenever needed, but the outstanding cumulative demand must never exceed
Long.MAX_VALUE
. An outstanding cumulative demand ofLong.MAX_VALUE
may be treated by theObservable
as "effectively unbounded".Whatever has been requested might be sent, so only signal demand for what can be safely handled.
An
Observable
can send less than is requested if the stream ends but then must emit eitherObserver.onError(Throwable)
orObserver.onComplete()
.- Parameters:
n
- the strictly positive number of elements to requests to the upstreamObservable
-
unsubscribe
void unsubscribe()
Deprecated.Request theObservable
to stop sending data and clean up resources.As this request is asynchronous data may still be sent to meet previously signalled demand after calling cancel.

is currently unsubscribed.- Returns:
true
if thisSubscription
is currently unsubscribed,false
