// AUTO-GENERATED DOCUMENTATION AND CLASS.
/**
* Settings class to configure an instance of {@link PredictionServiceStub}.
*
* <p>The default instance has everything set to sensible defaults:
*
* <ul>
* <li>The default service address (automl.googleapis.com) and default port (443) are used.
* <li>Credentials are acquired automatically through Application Default Credentials.
* <li>Retries are configured for idempotent methods but not for non-idempotent methods.
* </ul>
*
* <p>The builder of this class is recursive, so contained classes are themselves builders. When
* build() is called, the tree of builders is called to create the complete settings object.
*
* <p>For example, to set the total timeout of predict to 30 seconds:
*
* <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
* PredictionServiceStubSettings.Builder predictionServiceSettingsBuilder =
* PredictionServiceStubSettings.newBuilder();
* predictionServiceSettingsBuilder
* .predictSettings()
* .setRetrySettings(
* predictionServiceSettingsBuilder.predictSettings().getRetrySettings().toBuilder()
* .setTotalTimeout(Duration.ofSeconds(30))
* .build());
* PredictionServiceStubSettings predictionServiceSettings =
* predictionServiceSettingsBuilder.build();
