Interface ServiceLocator

  • All Known Implementing Classes:
    DefaultServiceLocator

    public interface ServiceLocator
    A simple infrastructure to programmatically wire the various components of the repository system together when it is used outside of an IoC container. Once a concrete implementation of a service locator has been setup, clients could use
     RepositorySystem repoSystem = serviceLocator.getService( RepositorySystem.class );
     
    to acquire the repository system. Components that implement Service will be given an opportunity to acquire further components from the locator, thereby allowing to create the complete object graph of the repository system.
