ServiceLocator Class
ServiceLocator is defined as:
public class ServiceLocator : IServiceContainer
{
public bool Lazy { get; set; }
public void AddService(Type serviceType,
ServiceCreatorCallback callback);
public void AddService(Type sourceType, Type serviceType,
ServiceCreatorCallback callback);
public void AddService(Type sourceType, Type serviceType,
object serviceInstance);
public void AddService(Type serviceType, object serviceInstance);
public object GetService(Type serviceType);
public object GetService(Type sourceType, Type serviceType);
public object GetService(object source, Type serviceType);
public object GetServiceExact(Type sourceType, Type serviceType);
public void RemoveService(Type serviceType);
public void RemoveService(Type sourceType, Type serviceType);
public event EventHandler ServicesChanged;
}
Services must be added to the locator so they may be accessed later. The AddService
methods are used to add services to the locator. Finding a service is handled by the
GetService methods. Services may be removed from the locator with the
