A type for which an instance of the EvaluatorContextDescriptor class must be created.


Type Description

An EvaluatorContextDescriptor object initialized for the specified type.


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.
