childSourceSettings

A collection of SnapSourceSettings objects representing the child snap sources of SnapSourceSettings.source, when the snap source is a SubtypeFeatureLayer. When this snap source is a SubtypeFeatureLayer, this collection contains a SnapSourceSettings object corresponding to each SubtypeSublayer of that layer, in the same order as the SubtypeFeatureLayer.subtypeSublayers collection.

This collection is empty when the SnapSourceSettings.source is not a SubtypeFeatureLayer.
