/**
 * Cloud Storage uses access control lists (ACLs) to manage object and
 * bucket access. ACLs are the mechanism you use to share objects with other
 * users and allow other users to access your buckets and objects.
 *
 * An ACL consists of one or more entries, where each entry grants permissions
 * to an entity. Permissions define the actions that can be performed against
 * an object or bucket (for example, `READ` or `WRITE`); the entity defines
 * who the permission applies to (for example, a specific user or group of
 * users).
 *
 * The `acl` object on a Bucket instance provides methods to get you a list of
 * the ACLs defined on your bucket, as well as set, update, and delete them.
 *
 * Buckets also have
 * {@link https://cloud.google.com/storage/docs/access-control/lists#default| default ACLs}
 * for all created files. Default ACLs specify permissions that all new
 * objects added to the bucket will inherit by default. You can add, delete,
 * get, and update entities and permissions for these as well with
 * {@link Bucket#acl.default}.

 * for all created files. You can add, delete, get, and update entities and
 * permissions for these as well. The method signatures and examples are all
 * the same, after only prefixing the method call with `default`.
 *
 * @example
 * ```
 * const {Storage} = require('@google-cloud/storage');

     *     Duplicate prefixes are omitted.
     * @param {string} [query.endOffset] Filter results to objects whose names are

     * @param {boolean} [query.includeFoldersAsPrefixes] If true, includes folders and

     *     or 1 page of results will be returned per call.
     * @param {string} [query.pageToken] A previously-returned page token
     *     representing part of the larger set of results to view.
     * @param {boolean} [query.softDeleted] If true, only soft-deleted object versions will be

     * @param {string} [query.startOffset] Filter results to objects whose names are
