Pagination¶
A lot of GetSocial methods support pagination. The pagination has the same appoach in all of them.
Count¶
Some paginated methods have a symmetric getCount method which allows to get the total count of elements matching that query.
val query = NotificationsQuery.withStatuses(NotificationStatus.UNREAD)
Notifications.getCount(query, { count: Int -> /** onSuccess **/}, { error: GetSocialError -> /** onError **/ })
var query = NotificationsQuery.WithStatuses(NotificationStatus.Unread);
Notifications.Count(query, (count) => { /** success **/ }, (error) => { /** error **/ });
Items List¶
To get a paginated items list you have to wrap the basic query into respective paging query. Paging query allows you to set a limit and also to add the pointer to the next page.
The result of such a call is an object, which contains the pointer to the next page and the list of items for a current page.
If the returned page is the last one, nextCursor will be an empty string. You can also use isLastPage method for convenience.
val query = NotificationsQuery.withStatuses(NotificationStatus.UNREAD)
val pagingQuery = PagingQuery(query)
Notifications.get(pagingQuery, { result: PagingResult<Notification> ->
val items = result.entries
if (!result.isLastPage) {
Notifications.get(pagingQuery.next(result.nextCursor()), { nextPageResult -> /** onSuccess **/ }, { error -> /** onError **/ })
}
}, { error: GetSocialError -> /** onError **/ })
var query = NotificationsQuery.WithStatuses(NotificationStatus.Unread);
var pagingQuery = new PagingQuery<NotificationsQuery>(query);
Notifications.Get(pagingQuery,
(result) => {
var items = result.Entries;
if (!result.IsLastPage)
{
Notifications.Get(pagingQuery.Next(result.NextCursor),
(nextPageResult) => { /** success **/ },
(error) => { /** error **/ });
}
},
(error) => { /** error **/ });
