ApplicativeFunctor.Applicatives, ApplicativeFunctor.ApplyFunctions<T>Value.ValueImpl<T>Convertable.SupplierToConvertable<T>| Modifier and Type | Method and Description |
|---|---|
<U> FutureWTValue<U> |
cast(java.lang.Class<? extends U> type)
Cast all elements in a stream to a given type, possibly throwing a
ClassCastException. |
<T2,R> FutureWTValue<R> |
combine(Value<? extends T2> app,
java.util.function.BiFunction<? super A,? super T2,? extends R> fn)
Lazily combine this ApplicativeFunctor with the supplied value via the supplied BiFunction
Example

emptyOptional() |
boolean |
equals(java.lang.Object o) |
MaybeTValue<A> |
filter(java.util.function.Predicate<? super A> test)
