Complex solution to work with pageable data, including sorting, filtering, actions, changing displayed columns, etc.

/**
* Structure of type is same as Spring Data Page type, thus server result
* can be pass to PageTable without transformation.
*/
interface Page<T> {
  content: T[];
  /* The number of the current page. Is always non-negative. */
  number: number;
  totalElements: number;
  totalPages: number;
}

const EMPTY_PAGE_IMPL: Page<unknown> = Object.freeze({
  content: [],
  number: 0,
  totalElements: 0,
  totalPages: 0,
});

export function emptyPage<T> (): Page<T> {
  return EMPTY_PAGE_IMPL as unknown as Page<T>;
}

export function singlePage<T> (items: T[]): Page<T> {
  return {
    content: items,
    number: 0,
    totalElements: items.length,
    totalPages: 1,
  };
}

export default Page;
