Deep Copy of Objects

[Kurt Guenther]

We've been using MapStruct in our project.   Great tool, so thank you to everybody that contributed. 

Question:  we've been hand coding deep copies of object graphs, but this seems like a use case that is very similar to MapStruct's core use cases.   Is this supported?

Hi,

It depends a bit on what exactly you mean by "deep copy", but
MapStruct definitely supports mapping nested object graphs. You'd
declare a mapping method for each pair of types in the source/target
graphs, and when figuring out that FooSource#bar needs to be mapped to
FooTarget#bar, MapStruct will generate an invocation of the
SourceBar-to-TargetBar mapping method.
