Class ExistingInstanceSetterWrapperForCollectionsAndMaps

  • All Implemented Interfaces:
    Assignment, Writable

    public class ExistingInstanceSetterWrapperForCollectionsAndMaps
    extends SetterWrapperForCollectionsAndMapsWithNullCheck
    This wrapper handles the situation where an assignment is done for an update method. In case of a pre-existing target 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. If there is no pre-existing target, or the target Collection / Map is not initialized (null) the setter is used to create a new Collection / Map with the copy constructor.
