aeat.domain.prorrata_register._protocols module¶

Domain-level repository Protocol for the cross-period IVA prorrata register.

Application-layer code that persists or loads the ProrrataRegister depends on ProrrataRegisterRepositoryProtocol, not on the concrete adapter-backed ProrrataRegisterRepository. This keeps the domain layer free of adapter imports while still providing a typed port surface.

class ProrrataRegisterRepositoryProtocol(*args, **kwargs)[source]¶

Bases: Protocol

Narrow domain-facing repository contract for the prorrata register.

Any object that provides load and to_secure_object_write over the singleton ProrrataRegister satisfies this protocol. The concrete secure-object-backed implementation is ProrrataRegisterRepository.

load()[source]¶

Return the persisted register or an empty register if absent.

Return type:: ProrrataRegister
Returns:: The ProrrataRegister loaded from storage.

to_secure_object_write(register)[source]¶

Return the SecureObjectWrite for register without committing it.

Return type:: SecureObjectWrite
Parameters:: register (ProrrataRegister)
