Module io.helidon.data
Package io.helidon.data

Interface Page<T>

Type Parameters:
T - query result type (entity or entity attribute)
All Superinterfaces:
Iterable<T>, Slice<T>
public interface Page<T> extends Slice<T>
Pageable query result as pages with total size of the result.

Page number and number of records returned on each page depends on values of the Slice.request() used to return current page.

Returned value of totalSize() and totalPages() requires another query to be executed while reading data from the database, so retrieving result as Slice should be faster than using Page.
