Methods

GeoJSONLayerProExtensions.ApplyEdits(this GeoJSONLayer, GeoJSONLayerApplyEditsEdits) Method

Applies edits to features in a layer.
param edits.addFeatures An array or a collection of features to be added. Values of non nullable fields must be provided when adding new features. Date fields must have numeric values representing universal time.
param edits.deleteFeatures An array or a collection of features, or objects to be deleted. When an array or collection of features is passed, each feature must have a valid objectId. When an array of objects is used, each object must have a valid objectId property.
