Examples with ListImagesRequest com.google.cloud.compute.v1.ListImagesRequest used on opensource projects

Example 1 with ListImagesRequest

use of com.google.cloud.compute.v1.ListImagesRequest in project java-docs-samples by GoogleCloudPlatform.

the class ListImages method listImagesByPage.

// [END compute_images_list]
// [START compute_images_list_page]
// Prints a list of all non-deprecated image names available in a given project,
// divided into pages as returned by the Compute Engine API.
public static void listImagesByPage(String project, int pageSize) throws IOException {
    // safely clean up any remaining background resources.
    try (ImagesClient imagesClient = ImagesClient.create()) {
        // Listing only non-deprecated images to reduce the size of the reply.
        ListImagesRequest imagesRequest = ListImagesRequest.newBuilder().setProject(project).setMaxResults(pageSize).setFilter("deprecated.state != DEPRECATED").build();
        // Use the `iteratePages` attribute of returned iterable to have more granular control of
        // iteration over paginated results from the API. Each time you want to access the
        // next page, the library retrieves that page from the API.
        int pageNumber = 1;
        for (ListPage page : imagesClient.list(imagesRequest).iteratePages()) {
            System.out.println("Page Number: " + pageNumber++);
            for (Image image : page.getValues()) {
                System.out.println(image.getName());
            }
        }
    }
}

Example 2 with ListImagesRequest

use of com.google.cloud.compute.v1.ListImagesRequest in project java-docs-samples by GoogleCloudPlatform.

the class ListImages method listImages.

// [START compute_images_list]
// Prints a list of all non-deprecated image names available in given project.
public static void listImages(String project) throws IOException {
    // safely clean up any remaining background resources.
    try (ImagesClient imagesClient = ImagesClient.create()) {
        // Listing only non-deprecated images to reduce the size of the reply.
        ListImagesRequest imagesRequest = ListImagesRequest.newBuilder().setProject(project).setMaxResults(100).setFilter("deprecated.state != DEPRECATED").build();
        // Although the `setMaxResults` parameter is specified in the request, the iterable returned
        // by the `list()` method hides the pagination mechanic. The library makes multiple
        // requests to the API for you, so you can simply iterate over all the images.
        int imageCount = 0;
        for (Image image : imagesClient.list(imagesRequest).iterateAll()) {
            imageCount++;
            System.out.println(image.getName());
        }
        System.out.printf("Image count in %s is: %s", project, imageCount);
    }
