static <T> rx.Observable<T> |
concatButIgnoreFirstSequence(rx.Observable<?> o1,
rx.Observable<T> o2)
Returns the concatenation of two
Observables but the first
sequence will be emitted in its entirety and ignored before o2 starts
emitting. |
static <T> RxUtil.CountingAction<T> |
counter()
Returns an
Action1 that increments a counter when the call method
is called. |
static <T> rx.Observable.Transformer<rx.Observable<T>,T> |
flatten()
Returns an
Observable.Transformer that flattens a sequence of
Observable into a flat sequence of the items from the
Observables. |
static <T> long |
getAndAddRequest(AtomicLongFieldUpdater<T> requested,
T object,
long n)
Adds
n to requested field and returns the value prior to
addition once the addition is successful (uses CAS semantics). |
static long |
getAndAddRequest(AtomicLong requested,
long n)
Adds
n to requested and returns the value prior to
addition once the addition is successful (uses CAS semantics). |

static <T> rx.Observer<? super T> |
log()
Logs errors and onNext at info level using slf4j
Logger. |
static <T> rx.functions.Func1<T,rx.Observable<Object>> |
toEmpty()
Returns a
Func1 that returns an empty Observable. |
