Create a DomainRegistry to access to domain objects (repository,factory, service, policy)

[tbouvet]

Closed #5

Feature to get a domain object programatically.

@Inject
DomainRegistry domain;

BonusCalculationPolicy myPolicy = domain.getPolicy(BonusCalculationPolicy.class, "qualifier-1");
AnotherPolicy<Client<Long>> myPolicy = domain.getPolicy(new TypeOf<AnotherPolicy<Client<Long>>>(){}, "qualifier-1");

RegistrationService myService = domain.getService(RegistrationService.class, "qualifier-1");

CustomerFactory<Customer> myFactory = domain.getFactory(Customer.class, "qualifier-1");

CustomerRepository<Customer,Long> myRepository = domain.getRepository(Customer.class, Long.class, aQualifierAnnotation.class);

Hi @tbouvet @pith , it could be a good opportunity to augment the "getService" , “getPolicy” feature in order to mimic Service as Kind of Closure (not a real closure but the spirit). Service with a constructor.

Constructor → TaxService(Long percent)

// 20% French TVA
TaxService nominalTaxService = domain.getService(TaxService.class, "qualifier-1" , 020l);

// Restaurant TVA Service
TaxService minimalTaxService = domain.getService(TaxService.class, "qualifier-1" , 0.05l);

The same for Policy. Policy with constructor could be obtained the same way.

This means another methods like this one

<T> T getService(Class<T> rawType, String qualifier, Object... args);

LGTM

@ejemba we think about this feature but in another issue. I think it would require a Guice assisted factory to do it.
