public class NestedAttributeMapping
extends AttributeMapping

This class represents AttributeMapping for attributes that are nested inside another complex attribute. The nested attributes would be features, or fake features, ie. complex attributes which types are wrapped with NonFeatureTypeProxy instances. The purpose of this class is to store nested built features so they can be retrieved when the parent feature is being built. Simple features are also stored for caching if a filter involving these nested features is run.
