Method Detail

identity

public static <T> rx.functions.Func1<T,T> identity()

alwaysTrue

public static <T> rx.functions.Func1<T,Boolean> alwaysTrue()

alwaysFalse

public static <T> rx.functions.Func1<T,Boolean> alwaysFalse()

constant

public static <T,R> rx.functions.Func1<T,R> constant(R r)

constant0

public static <T> rx.functions.Func0<T> constant0(T t)

not

public static <T> rx.functions.Func1<T,Boolean> not(rx.functions.Func1<T,Boolean> f)

just

public static <T> rx.functions.Func1<T,rx.Observable<T>> just()

add

public static <T extends Number> rx.functions.Func2<T,T,T> add()

Returns a Func2 that adds numbers. Useful for Observable.reduce but not particularly performant as it does instanceOf checks.

Type Parameters:

T - generic type of Number being added

Returns:

Func2 that adds numbers

collectStats

public static <T extends Number> rx.functions.Func2<Statistics,T,Statistics> collectStats()

toFunc2

public static <T> rx.functions.Func2<T,T,Integer> toFunc2(Comparator<T> comparator)
