    • entity

      public static com.sap.cds.CdsData entity(com.sap.cloud.sdk.datamodel.odata.client.request.ODataRequestResultGeneric result, com.sap.cds.reflect.CdsStructuredType resultType, com.sap.cloud.sdk.datamodel.odata.client.ODataProtocol protocol)
      Extracts an entity map from the OData result. OData V2 and V4 responses are normalized by mapping the response to the entity structure (e.g. removing results substructures). Also non entity keys and values are removed (e.g. _metadata or @odata.etag)
      Parameters:
      result - the OData result
      resultType - the structured type of the result
      protocol - the OData protocol version
      Returns:
      the entity data

    • noContent

      public static com.sap.cds.CdsData noContent(com.sap.cloud.sdk.datamodel.odata.client.request.ODataRequestResultGeneric result, Map<String,Object> data)
      Copies the original updated data to provide as a result for a "204 No Content" response. Takes care of updating the returned ETag on the data map.
      Parameters:
      result - the OData result
      data - the original data
      Returns:
      the copied data, with updated ETag

    • entityCollection

      public static List<com.sap.cds.CdsData> entityCollection(com.sap.cloud.sdk.datamodel.odata.client.request.ODataRequestResultGeneric result, com.sap.cds.reflect.CdsStructuredType resultType, com.sap.cloud.sdk.datamodel.odata.client.ODataProtocol protocol)
      Extracts a list of entity maps from the OData result. OData V2 and V4 responses are normalized by mapping the response to the entity structure (e.g. removing results substructures). Also non entity keys and values are removed (e.g. _metadata or @odata.etag)
      Parameters:
      result - the OData result
      resultType - the structured type of the result
      protocol - the OData protocol version
      Returns:
      the list of entity data

    • operation

      public static Object operation(com.sap.cloud.sdk.datamodel.odata.client.request.ODataRequestResultGeneric result, com.sap.cds.reflect.CdsType targetType, com.sap.cloud.sdk.datamodel.odata.client.ODataProtocol protocol, String operationName)
      Extracts the return value of an operation from the OData result. OData V2 and V4 responses are normalized by mapping the response to the entity structure (e.g. removing results substructures). Also non entity keys and values are removed (e.g. _metadata or @odata.etag)
      Parameters:
      result - the OData result
