ServiceDescriptor

class ServiceDescriptor

Public Types

using Ptr = std::unique_ptr<ServiceDescriptor>

Public Functions

inline ServiceDescriptor(const TypeId serviceTypeId, const TypeId implementationTypeId, std::unique_ptr<std::string> serviceKey, std::unique_ptr<std::string> implementationKey, const ServiceLifeTime lifeTime, IServiceFactory::Ptr implementationFactory, const ptrdiff_t castOffset = 0)

Construct a new service descriptor object.

Parameters:

  • serviceTypeId – - service type identifier

  • implementationTypeId – - service implementation type identifier, type must inhetit from service type

  • serviceKey – - service key

  • implementationKey – - service implementation key

  • lifeTime – - service life time: Singleton, Scoped or Transient

  • implementationFactory – - service implementation factory, can be nullptr in that case describer is treated as alias

  • castOffset – - cast offset is a difference in bytes between implementation pointer and casted service pointer, should be non zero for multiinheritance scenarios

inline TypeId getServiceTypeId() const

Get the service TypeId.

inline TypeId getImplementationTypeId() const

Get the service implementation TypeId.

inline const std::string *getServiceKey() const

Get the service key pointer.

inline const std::string *getImplementationKey() const

Get the service implementation key pointer.

inline ServiceLifeTime getLifeTime() const

Get the lifetime object.

inline const IServiceFactory *getImplementationFactory() const

inline ptrdiff_t getCastOffset() const

Get the service cast offset, non zero for multiinheritance.

inline bool isAlias() const

Check if service is alias (implementation factory is nullptr)
