/**
 * <p>Returns the event types that meet the specified filter criteria. You can use this API
 *          operation to find information about the Health event, such as the category, Amazon Web Services service, and event code. The metadata for each event appears in the <a href="https://docs.aws.amazon.com/health/latest/APIReference/API_EventType.html">EventType</a> object. </p>
 *          <p>If you don't specify a filter criteria, the API operation returns all event types, in no
 *          particular order. </p>
 *          <note>
 *             <p>This API operation uses pagination. Specify the <code>nextToken</code> parameter in the next request to return more results.</p>
 *          </note>
 * @example
 * Use a bare-bones client and the command you need to make an API call.
 * ```javascript
 * import { HealthClient, DescribeEventTypesCommand } from "@aws-sdk/client-health"; // ES Modules import
 * // const { HealthClient, DescribeEventTypesCommand } = require("@aws-sdk/client-health"); // CommonJS import
 * // import type { HealthClientConfig } from "@aws-sdk/client-health";
 * const config = {}; // type is HealthClientConfig
 * const client = new HealthClient(config);
 * const input = { // DescribeEventTypesRequest
 *   filter: { // EventTypeFilter
 *     eventTypeCodes: [ // EventTypeCodeList
 *       "STRING_VALUE",

 *   },
 *   locale: "STRING_VALUE",
 *   nextToken: "STRING_VALUE",
 *   maxResults: Number("int"),
 * };
 * const command = new DescribeEventTypesCommand(input);
 * const response = await client.send(command);
 * // { // DescribeEventTypesResponse
 * //   eventTypes: [ // EventTypeList
