final class AsyncSubject[T] extends Subject[T, T]

An AsyncSubject emits the last value (and only the last value) emitted by the source Observable, and only after that source Observable completes.

If the source terminates with an error, the AsyncSubject will not emit any items to subsequent subscribers, but will simply pass along the error notification from the source Observable.

    Permalink

    Forces a buffered asynchronous boundary.

    Forces a buffered asynchronous boundary.

    Internally it wraps the observer implementation given to subscribeFn into a BufferedSubscriber.

    Normally Monifu's implementation guarantees that events are not emitted concurrently, and that the publisher MUST NOT emit the next event without acknowledgement from the consumer that it may proceed, however for badly behaved publishers, this wrapper provides the guarantee that the downstream Observer given in subscribe will not receive concurrent events.

    WARNING: if the buffer created by this operator is unbounded, it can blow up the process if the data source is pushing events faster than what the observer can consume, as it introduces an asynchronous boundary that eliminates the back-pressure requirements of the data source. Unbounded is the default policy, see BufferPolicy for options.

    Concatenates the sequence of Observables emitted by the source into one Observable, without any transformation.

    You can combine the items emitted by multiple Observables so that they act like a single Observable by using this method.

    The difference between concat and merge is that concat cares about ordering of emitted items (e.g. all items emitted by the first observable in the sequence will come before the elements emitted by the second observable), whereas merge doesn't care about that (elements get emitted as they come). Because of back-pressure applied to observables, concat is safe to use in all contexts, whereas merge requires buffering.

    Merges the sequence of Observables emitted by the source into one Observable, without any transformation.

    You can combine the items emitted by multiple Observables so that they act like a single Observable by using this method.

    The difference between concat and merge is that concat cares about ordering of emitted items (e.g. all items emitted by the first observable in the sequence will come before the elements emitted by the second observable), whereas merge doesn't care about that (elements get emitted as they come). Because of back-pressure applied to observables, concat is safe to use in all contexts, whereas merge requires buffering.
