Inherited functions ForEach

Question

I have no idea on how to use this Inherited functions loop through objects from the featureLayer.
the objects are poles from the featurelayer. 
the docs lack a lot of explaining.

The functions come from the Iterable interface. FeatureQueryResult inherits from FeatureSet, which inherits from Kotlin Iterable. Please see the Kotlin Iterable documentation.
