How to map collections in Dozer

Question

I'd like to do something like: ``` ArrayList objects = new ArrayList(); ... DozerBeanMapper MAPPER = new DozerBeanMapper(); ... ArrayList newObjects = MAPPER.map(objects, ...); ``` Assuming: ```

com.me.CustomObject

com.me.NewObject

id id2 ``` I tried : ``` ArrayList holder = new ArrayList(); MAPPER.map(objects, holder); ``` but the holder object is empty. I also played with changing the second argument without any luck...

Accepted Answer

To quote:

"Nested collections are handled automatically, but you are correct that top level collections need to be iterated over. Currently there isn't a more elegant way to handle this."

Someone has figured a way to do it without a looping construct in your code base, but I think it's just easier (and more readable/maintainable) to put it in your code. Hopefully they'll add this ability sooner than later.
