Method Details

publisherWithSegments

public org.reactivestreams.Publisher<SegmentPublisherSupplier.Notification<R>> publisherWithSegments()

Description copied from interface: SegmentPublisherSupplier

A Publisher that will publish entries as originally configured from possibly remote sources. The published items will be wrapped in a SegmentPublisherSupplier.Notification which can be either an item or segment completion notification. The type can be verified by first invoking SegmentPublisherSupplier.Notification.isValue() or SegmentPublisherSupplier.Notification.isSegmentComplete() after which the value or segment information should be retrieved. Note that each value will also have a segment attributed to it which can be access by invoking SegmentPublisherSupplier.Notification.valueSegment().

Note that segment completion can be interwoven with values and some segments may have no items present. However, once a segment complete notification is encountered for a given segment no additional values will be published to the same subscriber for the given segment.

If segment information is not required, please use SegmentPublisherSupplier.publisherWithoutSegments() as implementations may have additional optimizations in place for when this information is not required.

Specified by:

publisherWithSegments in interface SegmentPublisherSupplier<I>

Returns:

a Publisher that publishes the resulting values with segment information

public org.reactivestreams.Publisher<R> publisherWithoutSegments()

Description copied from interface: SegmentPublisherSupplier

a Publisher that publishes the resulting values without corresponding segment information
