the class Database method setPermissions.

/**

 * // get the "example" database
 * Database db = client.database("example", false);
 *
 * // set read-only permissions
 * db.setPermissions(key.getKey(), EnumSet.<Permissions>of(Permissions._reader));
 * }

 * @param userNameorApikey the user or key to apply permissions to
 * @param permissions      permissions to grant
 * @throws UnsupportedOperationException if called on a database that does not provide the
