// AUTO-GENERATED DOCUMENTATION AND CLASS.
/**
 * Settings class to configure an instance of {@link BinauthzManagementServiceV1Stub}.
 *
 * <p>The default instance has everything set to sensible defaults:
 *
 * <ul>
 *   <li>The default service address (binaryauthorization.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 getPolicy to 30 seconds:
 *
 * <pre>{@code
 * BinauthzManagementServiceV1StubSettings.Builder binauthzManagementServiceV1SettingsBuilder =
 *     BinauthzManagementServiceV1StubSettings.newBuilder();
 * binauthzManagementServiceV1SettingsBuilder
 *     .getPolicySettings()
 *     .setRetrySettings(
 *         binauthzManagementServiceV1SettingsBuilder
 *             .getPolicySettings()
 *             .getRetrySettings()
 *             .toBuilder()
 *             .setTotalTimeout(Duration.ofSeconds(30))
 *             .build());
 * BinauthzManagementServiceV1StubSettings binauthzManagementServiceV1Settings =
 *     binauthzManagementServiceV1SettingsBuilder.build();
 * }</pre>
