Class IsEmpty
Represents an operator that determines whether the observable sequence is empty.
If the source sequence completes before returning any elements, the IsEmpty
operator will emit a single value true
before terminating successfully. If the source sequence emits any element, IsEmpty
will immediately emit a single value false
, terminate successfully, and cancel the subscription to the source sequence.
