extends java.lang.Object
Modifier and Type | Method and Description |
---|---|
StreamableT<T> |
filter(java.util.function.Predicate<? super T> test)
Filter the wrapped Streamable
|
<B> StreamableT<B> |
flatMap(java.util.function.Function<? super T,StreamableT<? extends B>> f)
Flat Map the wrapped Streamable
|
static <A> StreamableT<A> |
fromAnyM(AnyM<A> anyM)
|
static <A> StreamableT<A> |
fromStream(AnyM<java.util.stream.Stream<A>> monads)
Create a StreamableT from an AnyM that wraps a monad containing a Stream
|
static <U,R> java.util.function.Function<StreamableT<U>,StreamableT<R>> |
lift(java.util.function.Function<? super U,? extends R> fn)
Lift a function into one that accepts and returns an StreamableT
This allows multiple monad types to add functionality to existing functions and methods
e.g.
|
static <U1,U2,R> java.util.function.BiFunction<StreamableT<U1>,StreamableT<U2>,StreamableT<R>> |
lift2(java.util.function.BiFunction<? super U1,? super U2,? extends R> fn)
Lift a BiFunction into one that accepts and returns StreamableTs
This allows multiple monad types to add functionality to existing functions and methods
e.g.
|
<B> StreamableT<B> |
map(java.util.function.Function<? super T,? extends B> f)
Map the wrapped Streamable
|
static <A> StreamableT<A> |
of(AnyM<Streamable<A>> monads)
Construct an StreamableT from an AnyM that wraps a monad containing Streamables
|
StreamableT<T> |
peek(java.util.function.Consumer<? super T> peek)
Peek at the current value of the Streamable
