| bucket.core.PaginationSupport<T> |
Known Indirect Subclasses
| ManualTotalPaginationSupport<T> |
This class allows us to set the total number of items without
reading the size of the items list. |
| PagerPaginationSupport |
This class stores its items using a Pager - which cannot report the total
size of the result. |
| PaginationSupport<T> |
Where there are a _very_ large number of items to paginate (in othe order of 10,000's), loading them all up in memory from the db and then
handing them out to the user in a .subList fashion is not very efficient
In this scenario we only want to use this bean to compute our next and previous indexes. |
| UsernameToUserTranslatingPaginationSupport |
A special pagination support class to translate results of membership search to user objects. |
