// AUTO-GENERATED DOCUMENTATION AND CLASS.
/**
 * Service Description: Service for ingesting and querying logs.
 *
 * <p>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:
 *
 * <pre>{@code
 * // This snippet has been automatically generated and should be regarded as a code template only.
 * // It will require modifications to work:
 * // - It may require correct/in-range values for request initialization.
 * // - It may require specifying regional endpoints when creating the service client as shown in
 * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
 * try (LoggingClient loggingClient = LoggingClient.create()) {
 *   LogName logName = LogName.ofProjectLogName("[PROJECT]", "[LOG]");
 *   loggingClient.deleteLog(logName);
 * }
 * }</pre>
 *
 * <p>Note: close() needs to be called on the LoggingClient object to clean up resources such as
 * threads. In the example above, try-with-resources is used, which automatically calls close().

 * <p>Many parameters require resource names to be formatted in a particular way. To assist with

 * method to extract the individual identifiers contained within names that are returned.
 *
 * <p>This class can be customized by passing in a custom instance of LoggingSettings to create().
 * For example:
 *
 * <p>To customize credentials:
 *
 * <pre>{@code
 * // This snippet has been automatically generated and should be regarded as a code template only.
 * // It will require modifications to work:
 * // - It may require correct/in-range values for request initialization.
 * // - It may require specifying regional endpoints when creating the service client as shown in
 * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
 * LoggingSettings loggingSettings =
 *     LoggingSettings.newBuilder()
 *         .setCredentialsProvider(FixedCredentialsProvider.create(myCredentials))
 *         .build();
 * LoggingClient loggingClient = LoggingClient.create(loggingSettings);
 * }</pre>
 *
 * <p>To customize the endpoint:
 *
 * <pre>{@code
 * // This snippet has been automatically generated and should be regarded as a code template only.
 * // It will require modifications to work:
 * // - It may require correct/in-range values for request initialization.
 * // - It may require specifying regional endpoints when creating the service client as shown in
 * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
 * LoggingSettings loggingSettings = LoggingSettings.newBuilder().setEndpoint(myEndpoint).build();
 * LoggingClient loggingClient = LoggingClient.create(loggingSettings);
 * }</pre>

   * @param resource Optional. A default monitored resource object that is assigned to all log
   *     entries in `entries` that do not specify a value for `resource`. Example:
   *     <p>{ "type": "gce_instance", "labels": { "zone": "us-central1-a", "instance_id":

   *     in `entries`. If a log entry already has a label with the same key as a label in this
   *     parameter, then the log entry's label is not changed. See
   *     [LogEntry][google.logging.v2.LogEntry].
   * @param entries Required. The log entries to send to Logging. The order of log entries in this

   *     fields are copied into those log entries in this list that do not include values for their
   *     corresponding fields. For more information, see the [LogEntry][google.logging.v2.LogEntry]
   *     type.
   *     <p>If the `timestamp` or `insert_id` fields are missing in log entries, then this method
   *     supplies the current time or a unique identifier, respectively. The supplied values are
   *     chosen so that, among the log entries that did not supply their own values, the entries
   *     earlier in the list will sort before the entries later in the list. See the `entries.list`
   *     method.

   *     period](https://cloud.google.com/logging/quotas) in the past or more than 24 hours in the
   *     future will not be available when calling `entries.list`. However, those log entries can

   * Writes log entries to Logging. This API method is the only way to send log entries to Logging.

   *
   * <p>Sample code:
   *
   * <pre>{@code
   * // This snippet has been automatically generated and should be regarded as a code template only.
   * // It will require modifications to work:
   * // - It may require correct/in-range values for request initialization.

   *   WriteLogEntriesResponse response =
   *       loggingClient.writeLogEntries(logName, resource, labels, entries);
   * }
   * }</pre>
   *
   * @param logName Optional. A default log resource name that is assigned to all log entries in
   *     `entries` that do not specify a value for `log_name`:
   *     <ul>
   *       <li>`projects/[PROJECT_ID]/logs/[LOG_ID]`
   *       <li>`organizations/[ORGANIZATION_ID]/logs/[LOG_ID]`
   *       <li>`billingAccounts/[BILLING_ACCOUNT_ID]/logs/[LOG_ID]`
   *       <li>`folders/[FOLDER_ID]/logs/[LOG_ID]`
   *     </ul>
   *     <p>`[LOG_ID]` must be URL-encoded. For example:
   *     <p>"projects/my-project-id/logs/syslog"
   *     "organizations/123/logs/cloudaudit.googleapis.com%2Factivity"
   *     <p>The permission `logging.logEntries.create` is needed on each project, organization,
   *     billing account, or folder that is receiving new log entries, whether the resource is
   *     specified in `logName` or in an individual log entry.
   * @param resource Optional. A default monitored resource object that is assigned to all log
   *     entries in `entries` that do not specify a value for `resource`. Example:
   *     <p>{ "type": "gce_instance", "labels": { "zone": "us-central1-a", "instance_id":
   *     "00000000000000000000" }}
   *     <p>See [LogEntry][google.logging.v2.LogEntry].
   * @param labels Optional. Default labels that are added to the `labels` field of all log entries
   *     in `entries`. If a log entry already has a label with the same key as a label in this
   *     parameter, then the log entry's label is not changed. See
   *     [LogEntry][google.logging.v2.LogEntry].
   * @param entries Required. The log entries to send to Logging. The order of log entries in this
   *     list does not matter. Values supplied in this method's `log_name`, `resource`, and `labels`
   *     fields are copied into those log entries in this list that do not include values for their
   *     corresponding fields. For more information, see the [LogEntry][google.logging.v2.LogEntry]
   *     type.
   *     <p>If the `timestamp` or `insert_id` fields are missing in log entries, then this method
   *     supplies the current time or a unique identifier, respectively. The supplied values are
   *     chosen so that, among the log entries that did not supply their own values, the entries
   *     earlier in the list will sort before the entries later in the list. See the `entries.list`
   *     method.
   *     <p>Log entries with timestamps that are more than the [logs retention
   *     period](https://cloud.google.com/logging/quotas) in the past or more than 24 hours in the
   *     future will not be available when calling `entries.list`. However, those log entries can
   *     still be [exported with
   *     LogSinks](https://cloud.google.com/logging/docs/api/tasks/exporting-logs).
   *     <p>To improve throughput and to avoid exceeding the [quota
   *     limit](https://cloud.google.com/logging/quotas) for calls to `entries.write`, you should
   *     try to include several log entries in this list, rather than calling this method for each
   *     individual log entry.
