bufferFactor property

double get bufferFactor

The factor used to calculate a buffered extent around the current visible area when requesting features from a service.

New features are requested from the service if the visible area of the ArcGISMapViewController exceeds the buffered extent. A change in the visible area can result from any user interaction with the ArcGISMapViewController, such as a pan or zoom action. The buffer factor is applied when the FeatureRequestMode is in either FeatureRequestMode.onInteractionCache or FeatureRequestMode.onInteractionNoCache.

The default value is 2 (twice the current extent). The maximum value is 10. If it is set to 0 or 1, the buffered extent will equal the visible map area.
