Type Parameters:

AggregateRoot - the aggregate root

Dto - the dto type

All Known Implementing Classes:

AbstractBaseAssembler, BaseAssembler, BaseTupleAssembler

public interface Assembler<AggregateRoot,Dto>

This interface represents the Assembler concepts between an aggregate and a DTO.

This is a helper to transform an aggregate to a DTO and vice versa.

Underlying class will have to provide the gateway implementation.
