Abstract Value Members

  1. abstract def getFeed(startSequenceNr: Long, count: Int, forward: Boolean)(implicit executionContext: ExecutionContext, context: C): Future[Option[FeedPage[E]]]

    Retrieves a page of the feed.

    Retrieves a page of the feed.

    startSequenceNr

    the starting entry's sequence number (exclusive), should not be returned in the feed page

    count

    the number of entries to return in the feed page, can be less if page is incomplete

    forward

    if true navigate to 'previous' elements in feed (towards head of feed) else ('backward') navigate to 'next' elements in feed (towards last page of feed)

    returns

    the feed page or None if the page is not found

  2. abstract def getHeadOfFeed(pageSize: Int)(implicit executionContext: ExecutionContext, context: C): Future[FeedPage[E]]

    Retrieves the head of the feed.

    Retrieves the head of the feed. This is the first page containing the most recent entries

    pageSize

    the maximum number of feed entries to return. The page could contain less entries

    returns

    the head of the feed

  3. abstract def push(uuid: String, entry: E)(implicit context: C): Future[Unit]
  4. abstract def push(entries: Iterable[E])(implicit context: C): Future[Unit]

    push a list of entries to the feed

    push a list of entries to the feed

    entries

    the entries to push to the feed
