public class ReadOnlyDomainListTypeConverter
extends AbstractListTypeConverter

Type converter for converting lists with object of specific type. Can only be used as declared converter.

Similar to ReadOnlyDomainTypeConverter this does a full conversion from domain to transfer object but will only find the objects and not update the fields when converting to the domain object. This way list membership is updated, but the domain objects remain unmodified.
