Method Details

of

public static <T> PaginationResult<T> of(List<T> elements,
 long count,
 PaginationParameter currentPage)

Creates an instance using the already computed list of {code}elements{/code} and {code}count{/count}, together with the {code}currentPage{/code} PaginationParameter used to build it.

Type Parameters:

T - any object type

Parameters:

elements - the list of elements

count - the total number of elements (through all pages)

currentPage - the PaginationParameter used to build this paged result

Returns:

the built instance of PaginationResult

fromFullList

public static <T> PaginationResult<T> fromFullList(List<T> fullList,
