Concrete methods

def contramap[B](f: B => A): Observer[B]

Given a contravariant mapping function, transform the source Observer by transforming the input.

Given a contravariant mapping function, transform the source Observer by transforming the input.

def feed(iterable: Iterable[A])(implicit s: Scheduler): Future[Ack]

Feeds the Observer instance with elements from the given collection, respecting the contract and returning a Future[Ack] with the last acknowledgement given after the last emitted element.

Feeds the Observer instance with elements from the given collection, respecting the contract and returning a Future[Ack] with the last acknowledgement given after the last emitted element.

Value parameters:
iterable

is the collection of items to push downstream

def feed(subscription: BooleanCancelable, iterable: Iterable[A])(implicit s: Scheduler): Future[Ack]

Feeds the Observer instance with elements from the given collection, respecting the contract and returning a Future[Ack] with the last acknowledgement given after the last emitted element.

Feeds the Observer instance with elements from the given collection, respecting the contract and returning a Future[Ack] with the last acknowledgement given after the last emitted element.

Value parameters:
iterable

is the collection of items to push downstream

subscription

is a BooleanCancelable that will be queried for its cancellation status, but only on asynchronous boundaries, and when it is seen as being isCanceled, streaming is stopped

def feed(iterator: Iterator[A])(implicit s: Scheduler): Future[Ack]

Feeds the Observer instance with elements from the given collection, respecting the contract and returning a Future[Ack] with the last acknowledgement given after the last emitted element.

Feeds the Observer instance with elements from the given collection, respecting the contract and returning a Future[Ack] with the last acknowledgement given after the last emitted element.

Value parameters:
iterator

is the collection of items to push downstream

def feed(subscription: BooleanCancelable, iterator: Iterator[A])(implicit s: Scheduler): Future[Ack]

Feeds the Observer instance with elements from the given collection, respecting the contract and returning a Future[Ack] with the last acknowledgement given after the last emitted element.

Feeds the Observer instance with elements from the given collection, respecting the contract and returning a Future[Ack] with the last acknowledgement given after the last emitted element.

Value parameters:
iterator

is the collection of items to push downstream

subscription

is a BooleanCancelable that will be queried for its cancellation status, but only on asynchronous boundaries, and when it is seen as being isCanceled, streaming is stopped

def onNextAll(xs: Iterable[A])(implicit s: Scheduler): Future[Ack]

Feeds the Observer instance with elements from the given collection, respecting the contract and returning a Future[Ack] with the last acknowledgement given after the last emitted element.

Feeds the Observer instance with elements from the given collection, respecting the contract and returning a Future[Ack] with the last acknowledgement given after the last emitted element.

Value parameters:
xs

the traversable object containing the elements to feed into our observer.

def toReactive(implicit s: Scheduler): Subscriber[A]

Transforms the source Observer into a org.reactivestreams.Subscriber instance as defined by the Reactive Streams specification.

Transforms the source Observer into a org.reactivestreams.Subscriber instance as defined by the Reactive Streams specification.

def toReactive(requestCount: Int)(implicit s: Scheduler): Subscriber[A]

Transforms the source Observer into a org.reactivestreams.Subscriber instance as defined by the Reactive Streams specification.

Transforms the source Observer into a org.reactivestreams.Subscriber instance as defined by the Reactive Streams specification.

Value parameters:
requestCount

a strictly positive number, representing the size of the buffer used and the number of elements requested on each cycle when communicating demand, compliant with the reactive streams specification
