Pagerfanta defines Pagerfanta\Adapter\AdapterInterface which is the abstraction layer for any system to provide data to a Pagerfanta instance to support pagination lists.

The interface requires two methods to be implemented:

• getNbResults: Retrieves a count of the total number of items in the list
• getSlice: Retrieves the list of items in the current page of the paginated list

<?php

namespace Pagerfanta\Adapter;

interface AdapterInterface
{
    /**
     * Returns the number of results for the list.
     *
     * @return int
     */
    public function getNbResults();

    /**
     * Returns an slice of the results representing the current page of items in the list.
     *
     * @param int $offset
     * @param int $length
     *
     * @return iterable
     */
    public function getSlice($offset, $length);
}
