↳ | bucket.core.actions.PagerPaginationSupport |
This class stores its items using a Pager - which cannot report the total
size of the result. The getCurrentPage()
returns
a list of objects currently loaded in memory, which can return a size()
.
This number is imprecise, however, and is used as functional approximation. For various reasons explained
in the {#link Pager} javadoc, the only way to gain an accurate total size from a {#link Pager} is by using
its iterator and keeping count of each object.
If you have a regular, average sized list of items then use PaginationSupport
.
