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 an 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.
