Examples with Pagination com.netflix.titus.grpc.protogen.Pagination used on opensource projects

Example 1 with Pagination

use of com.netflix.titus.grpc.protogen.Pagination in project titus-control-plane by Netflix.

the class PageAggregationUtil method takeCombinedPage.

static <T> Pair<List<T>, Pagination> takeCombinedPage(Page requested, List<T> combinedItems, Pagination combinedPagination, Comparator<T> cursorComparator, Function<T, String> cursorFactory) {
    List<T> sorted = combinedItems.stream().sorted(cursorComparator).collect(Collectors.toList());
    int lastItemOffset = Math.min(sorted.size(), requested.getPageSize());
    List<T> pageItems = sorted.subList(0, lastItemOffset);
    String cursor = sorted.isEmpty() ? "" : cursorFactory.apply(pageItems.get(pageItems.size() - 1));
    // first item position relative to totalItems from all Cells
    int firstItemPosition = Math.max(0, combinedPagination.getCursorPosition() - (sorted.size() - 1));
    int pageNumber = firstItemPosition / requested.getPageSize();
    Pagination finalPagination = Pagination.newBuilder(combinedPagination).setCurrentPage(Page.newBuilder(requested).setPageNumber(pageNumber)).setCursor(cursor).setCursorPosition(firstItemPosition + lastItemOffset - 1).setHasMore(combinedPagination.getHasMore() || lastItemOffset < sorted.size()).build();
    return Pair.of(pageItems, finalPagination);
}

Example 2 with Pagination

use of com.netflix.titus.grpc.protogen.Pagination in project titus-control-plane by Netflix.

the class GatewayJobServiceGatewayTest method testCombineActiveAndArchiveTaskResultSet.

private void testCombineActiveAndArchiveTaskResultSet(Function<Pagination, TaskQuery> queryFunction, Function<Integer, TaskQueryResult> activePageResultFunction) {
    // First page
    TaskQueryResult combinedResult = testCombineForFirstPage();
    // Iterate using page numbers
    // Archive tasks first.
    Pagination lastPagination = combinedResult.getPagination();
    for (int p = 1; p < ARCHIVED_TASKS_COUNT / PAGE_SIZE; p++) {
        TaskQuery cursorQuery = queryFunction.apply(lastPagination);
        TaskQueryResult cursorResult = GatewayJobServiceGateway.combineTaskResults(cursorQuery, activePageResultFunction.apply(0), ARCHIVED_TASKS);
        checkCombinedResult(cursorResult, ARCHIVED_TASKS.subList(p * PAGE_SIZE, (p + 1) * PAGE_SIZE));
        lastPagination = cursorResult.getPagination();
    }
    // Now fetch the active data
    for (int p = 0; p < JOB_SIZE / PAGE_SIZE; p++) {
        TaskQuery cursorQuery = queryFunction.apply(lastPagination);
        TaskQueryResult cursorResult = GatewayJobServiceGateway.combineTaskResults(cursorQuery, activePageResultFunction.apply(p), ARCHIVED_TASKS);
        checkCombinedResult(cursorResult, ACTIVE_TASKS.subList(p * PAGE_SIZE, (p + 1) * PAGE_SIZE));
        lastPagination = cursorResult.getPagination();
    }
