#Remarks
When implementing the IObjectSpace interface in the BaseObjectSpace class’ descendant, you don’t have to implement this method. The BaseObjectSpace.GetEvaluatorContextDescriptor method creates an instance of the DevExpress.Data.Filtering.Helpers.EvaluatorContextDescriptorDefault class. However, if you need to create a custom descriptor, override the BaseObjectSpace.GetEvaluatorContextDescriptor method.
