Public Functions

ServiceDescriptor(TypeId serviceTypeId, TypeId implementationTypeId, ServiceLifeTime lifeTime, IServiceFactory::Ptr implementationFactory, 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

• 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

TypeId getServiceTypeId() const

Get the service TypeId.

TypeId getImplementationTypeId() const

Get the service implementation TypeId.

ServiceLifeTime getLifeTime() const

Get the lifetime object.

const IServiceFactory &getImplementationFactory() const

Get the service implementation factory.

ptrdiff_t getCastOffset() const

Get the service cast offset, non zero for multiinheritance.

bool isAlias() const

Check if service is alias (implementation factory is nullptr)
