Hi David,
Yes,
MyDTO copy = cnv.convert( dto ).to( MyDTO.class );
will create a copy. Whenever a conversion is done to a key-value based type
(map, dictionary, interface, annotation, JavaBean or DTO) the converter
will create a copy which can be owned and possibly further modified by the
caller.
I will certainly bring the idea of adding an explicit copy() method to the
Converter design discussions at OSGi.
Cheers and thanks for the feedback!
David
