Map multiple fields to a single one

[laurentthiebaudezm]

Hi,

I have a structure like:

class Source {
  val field1: ...
  val field2: ...
 val otherField: ...
}

class Destination {
  val singleField: TargetField
  val otherField: ...
}

I'd like to create a mapping from (field1 + field2) to singleField (keeping btw otherField).

I can easily create a Transformer to handle this:

class MyTransformer : MappingTransformer<Source, TargetField> {

but I cannot declare the mapping using this transformer, then:

.withMapping<Source, Destination> {
    Source::Source mappedTo Destination::otherField
       ???  mappedTo Destination::singleField withTransformer MyTransformer::class
    }

This is probably not the right way to achieve my goal. How could do?

(I guess I could also use a Decorator but then my singleField should be declared as a var which is not acceptable in my case)

any update for this issue?

Hi @fjr619, due to lack of time we're currently not actively developing ShapeShift except for features we actively need in our projects. I think adding some sort of separate annotation/mechanism for a composite mapping is a welcome edition. If you'd like, you can pick it up yourself.
