DtoOf (business-specs 4.3.1 API)

```
@Documented
@Retention(RUNTIME)
@Target({TYPE,ANNOTATION_TYPE})
public @interface DtoOf
```
This annotation allows to declare a relation between a class acting as DTO and the aggregate (or tuple of aggregates) it represents. It is only required by the business framework if you don't have an explicit Assembler implementation for the types involved, as it allows it to generate a default generic implementation.
Usage:
```
 @DtoOf(Customer.class)
  public class CustomerDto {
      ...
  }
 
```
Depending upon the assembler default implementation(s) present in the classpath, a generic assembler can be injected with a qualified Assembler interface:
```
 public class SomeClass {
    @Inject
    @SomeQualifier
     Assembler<Customer, CustomerDto> customerAssembler;
 }
 
```
