// AUTO-GENERATED DOCUMENTATION AND SERVICE
/**
 * Service Description: Entities are extracted from user input and represent parameters that are
 * meaningful to your application. For example, a date range, a proper name such as a geographic
 * location or landmark, and so on. Entities represent actionable data for your application.
 *
 * <p>When you define an entity, you can also include synonyms that all map to that entity. For
 * example, "soft drink", "soda", "pop", and so on.
 *
 * <p>There are three types of entities:
 *
 * <p>&#42; &#42;&#42;System&#42;&#42; - entities that are defined by the Dialogflow API for common
 * data types such as date, time, currency, and so on. A system entity is represented by the
 * `EntityType` type.
 *
 * <p>&#42; &#42;&#42;Developer&#42;&#42; - entities that are defined by you that represent
 * actionable data that is meaningful to your application. For example, you could define a
 * `pizza.sauce` entity for red or white pizza sauce, a `pizza.cheese` entity for the different
 * types of cheese on a pizza, a `pizza.topping` entity for different toppings, and so on. A
 * developer entity is represented by the `EntityType` type.
 *
 * <p>&#42; &#42;&#42;User&#42;&#42; - entities that are built for an individual user such as
 * favorites, preferences, playlists, and so on. A user entity is represented by the
 * [SessionEntityType][google.cloud.dialogflow.v2.SessionEntityType] type.
 *
 * <p>For more information about entity types, see the [Dialogflow
 * documentation](https://dialogflow.com/docs/entities).
 *
 * <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>
 * try (EntityTypesClient entityTypesClient = EntityTypesClient.create()) {
 *   EntityTypeName name = EntityTypeName.of("[PROJECT]", "[ENTITY_TYPE]");
 *   EntityType response = entityTypesClient.getEntityType(name);
 * }
 * </code>
 * </pre>
 *
 * <p>Note: close() needs to be called on the entityTypesClient object to clean up resources such as
 * threads. In the example above, try-with-resources is used, which automatically calls close().
 *
 * <p>The surface of this class includes several types of Java methods for each of the API's
 * methods:
 *
 * <ol>
 *   <li> A "flattened" method. With this type of method, the fields of the request type have been
 *       converted into function parameters. It may be the case that not all fields are available as
 *       parameters, and not every API method will have a flattened method entry point.
 *   <li> A "request object" method. This type of method only takes one parameter, a request object,
 *       which must be constructed before the call. Not every API method will have a request object
 *       method.
 *   <li> A "callable" method. This type of method takes no parameters and returns an immutable API
 *       callable object, which can be used to initiate calls to the service.
 * </ol>
 *
 * <p>See the individual methods for example code.
 *
 * <p>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 parse
 * 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 EntityTypesSettings to
 * create(). For example:
 *
 * <p>To customize credentials:
 *
 * <pre>
 * <code>
 * EntityTypesSettings entityTypesSettings =
 *     EntityTypesSettings.newBuilder()
 *         .setCredentialsProvider(FixedCredentialsProvider.create(myCredentials))
 *         .build();
 * EntityTypesClient entityTypesClient =
 *     EntityTypesClient.create(entityTypesSettings);
 * </code>
 * </pre>
 *
 * To customize the endpoint:
 *
 * <pre>
 * <code>
 * EntityTypesSettings entityTypesSettings =
 *     EntityTypesSettings.newBuilder().setEndpoint(myEndpoint).build();
 * EntityTypesClient entityTypesClient =
 *     EntityTypesClient.create(entityTypesSettings);
 * </code>
 * </pre>
