/**
 * Service Description: Service for ingesting and querying logs.
 *
 * EXPERIMENTAL: This client library class has not yet been declared GA (1.0). This means that
 * even though we intend the surface to be stable, we may make backwards incompatible changes
 * if necessary.
 *
 * This class provides the ability to make remote calls to the backing service through method
 * calls that map to API methods. Sample code to get started:
 *
 * ```
 * $loggingServiceV2Client = new LoggingServiceV2Client();
 * try {
 *     $formattedLogName = $loggingServiceV2Client->logName('[PROJECT]', '[LOG]');
 *     $loggingServiceV2Client->deleteLog($formattedLogName);
 * } finally {
 *     $loggingServiceV2Client->close();
 * }
 * ```
 *
 * Many parameters require resource names to be formatted in a particular way. To assist
 * with these names, this class includes a format method for each type of name, and additionally
 * a parseName method to extract the individual identifiers contained within formatted names
 * that are returned by the API.
 *

     * @param string[] $resourceNames Required. Names of one or more parent resources from which to
     *                                retrieve log entries:
     *
     *     "projects/[PROJECT_ID]"
     *     "organizations/[ORGANIZATION_ID]"
     *     "billingAccounts/[BILLING_ACCOUNT_ID]"
     *     "folders/[FOLDER_ID]"
     *
     * Projects listed in the `project_ids` field are added to this list.
     * @param array $optionalArgs {
     *                            Optional.
     *
     *     @type string[] $projectIds
     *          Deprecated. Use `resource_names` instead.  One or more project identifiers
     *          or project numbers from which to retrieve log entries.  Example:
     *          `"my-project-1A"`. If present, these project identifiers are converted to
     *          resource name format and added to the list of resources in
     *          `resource_names`.
     *     @type string $filter
     *          Optional. A filter that chooses which log entries to return.  See [Advanced
     *          Logs Filters](https://cloud.google.com/logging/docs/view/advanced_filters).  Only log entries that
     *          match the filter are returned.  An empty filter matches all log entries in
     *          the resources listed in `resource_names`. Referencing a parent resource
     *          that is not listed in `resource_names` will cause the filter to return no
     *          results.
     *          The maximum length of the filter is 20000 characters.
     *     @type string $orderBy
     *          Optional. How the results should be sorted.  Presently, the only permitted
     *          values are `"timestamp asc"` (default) and `"timestamp desc"`. The first
     *          option returns entries in order of increasing values of
     *          `LogEntry.timestamp` (oldest first), and the second option returns entries
     *          in order of decreasing timestamps (newest first).  Entries with equal
     *          timestamps are returned in order of their `insert_id` values.
     *     @type int $pageSize
     *          The maximum number of resources contained in the underlying API
     *          response. The API may return fewer values in a page, even if
     *          there are additional values to be retrieved.
     *     @type string $pageToken
     *          A page token is used to specify a page of values to be returned.
     *          If no page token is specified (the default), the first page
     *          of values will be returned. Any page token used here must have
     *          been generated by a previous call to the API.
     *     @type RetrySettings|array $retrySettings
     *          Retry settings to use for this call. Can be a
     *          {@see Google\ApiCore\RetrySettings} object, or an associative array
     *          of retry settings parameters. See the documentation on
