class ServiceDescriber#

This is helper factory class for constructing ServiceDescriptor.

Public Static Functions

template<class TService, class TImplementation = TService> static inline ServiceDescriptor describeSingleton()#

Creates service descriptor with: lifetime - singleton, serviceTypeId - typeid(TService), implementationTypeId - typeid(TImplementation), factory - default factory using TImplementation constructor

Example:

ServiceDescriptor descriptor1 = ServiceDescriber::describeSingleton<TestClass>();
ServiceDescriptor descriptor2 = ServiceDescriber::describeSingleton<BaseClass, ImplementationClass>();
