    public abstract class Request
extends Object
implements Serializable
    This class represents the Cognite Data Fusion API request parameters. The available parameters depend on which API endpoint you are working towards. The parameters mirrors what is available in the api. For example, which filters you can use. Please refer to the Cognite API documentation https://docs.cognite.com/api/v1/ for reference.
