public interface FuseToFlowable<@NonNull T>
Interface indicating a operator implementation can be macro-fused back to Flowable in case the operator goes from Flowable to some other reactive type and then the sequence calls for toFlowable again:Single<Integer> single = Flowable.range(1, 10).reduce((a, b) -> a + b); Flowable<Integer> flowable = single.toFlowable();
Single.toFlowable()
will check for this interface and call thefuseToFlowable()
to return a Flowable which could be the Flowable-specific implementation of reduce(BiFunction).This causes a slight overhead in assembly time (1 instanceof check, 1 operator allocation and 1 dropped operator) but does not incur the conversion overhead at runtime.
