Class Request

java.lang.Object
com.cognite.client.Request
All Implemented Interfaces:
Serializable
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.

    • withRequestParameters

      public Request withRequestParameters(Map<String,Object> requestParameters)
      Adds the complete request parameter structure based on Java objects. Calling this method will overwrite any previously added parameters. - All keys must be String. - Values can be primitives or containers - Valid primitives are String, Integer, Double, Float, Long, Boolean. - Valid containers are Map (Json Object) and List (Json array).

      Example:

       
     Request.create().withRequestParameters(ImmutableMap.of("limit", 2))
      Parameters:

    • withItems

      public Request withItems(List<? extends Map<String,Object>> items)
      Sets the items array to the specified input list. The list represents an array of objects via Java Map. That is, an instance of Map equals a Json object. For most write operations the maximum number of items per request is 1k. For time series datapoints the maximum number of items is 10k, with a maximum of 100k data points.

      Example:

       
      List<Map<String, Object>> requestItems = new ArrayList<>();
      Map<String, Object> requestItem = new HashMap<>();
      requestItem.put("externalId", 1);
      requestItems.add(requestItem);
      Request parameters = Request.create()
                  .withItems(requestItems);
      Parameters:
      items -
      Returns:
      The request object with the parameter applied.
