public class GetterWrapperForCollectionsAndMaps
extends WrapperForCollectionsAndMaps

This wrapper handles the situation were an assignment must be done via a target getter method because there is no setter available. The wrapper checks if there is a collection or map initialized on the target bean (not null). If so it uses the addAll (for collections) or putAll (for maps). The collection / map is cleared in case of a pre-existing target MappingTargetbefore adding the source entries. The goal is that the same collection / map is used as target. Nothing can be added if the getter on the target returns null.
