Annotation Type ExternalDomain

@Target(value=TYPE)
 @Retention(value=RUNTIME)
public @interface ExternalDomain

Indicates to handle an arbitrary class as if it was a Domain annotated class.

The annotated class must implement DomainConverter.

In the bellow code, the SalaryConverter class handles the Salary class as a Domain annotated class:

 @ExternalDomain
 public class SalaryConverter implements DomainConverter<Salary, BigDecimal> {

     public BigDecimal fromDomainToValue(Salary domain) {
         return domain.getValue();
     }

     public Salary fromValueToDomain(BigDecimal value) {
         return new Salary(value);
     }
 }
 

The annotated instance is required to be thread safe.
