Interface ServiceFactoryInterface

All Known Implementing Classes:
AbstractServiceFactory, DiscoveryServiceFactory, EventBrokerDiscoveryServiceFactory, EventBrokerServiceFactory, SessionServiceFactory, StoredProcessServiceFactory
public interface ServiceFactoryInterface
An interface used to acquire an implementation of a service based upon a desired service configuration. Each service must provide its own factory implementation.

A naming convention of "XxxServiceFactory.java" is suggested where "Xxx" represents the service type. For example, a factory used to get an instance of a AuthenticationServiceInterface would be named "AuthenticationServiceFactory".

An abstract implementation of a service factory AbstractServiceFactory is available to be subclassed.

      Gets a service initialized with the specified service configuration.

      RemoteServiceInterface is the base interface implemented by all services.

      Parameters:
      serviceConfiguration - Service configuration.
      discoveryService - This discovery service which may be used to locate other services. A service which can be discovered must register itself with this discovery service.
      Returns:
      service implementation
      Throws:
      ServiceException - if unable to obtain a service based upon the specified configuration.

    • isSingletonFactory

      boolean isSingletonFactory()
      Determines whether or not the service factory allows only one instance of a service per application.
      Returns:
      false if this factory allows creation of multiple services by calling getService method or true if only one service is allowed per application.
