note description: "[ Shared access to a global service provider. Note: `service_provider' provides uniformed access to a global service heap. There should only be one heap per application to avoid confusion. Any class requiring access to a service should inherit or use {SHARED_SERVICE_PROVIDER} as a client. On first initialization a service heap {SERVICE_HEAP} will be created to store and maintain a list of services. After initialization two services will be registered. * {SERVICE_CONTAINER_S} provides access to the global service container by-passing any chained container. * {SERVICE_PROVIDER_S} provides access to the global service provider by-passing any chained provider. ]" legal: "See notice at end of class." status: "See notice at end of class."; date: "$Date$"; revision: "$Revision $" class SHARED_SERVICE_PROVIDER feature -- Access frozen service_provider: SERVICE_PROVIDER_I -- Shared access to the global service provider. local l_provider: SERVICE_HEAP once create l_provider.make Result := l_provider l_provider.register_with_activator ({detachable SERVICE_CONTAINER_S}, agent (ia_container: attached SERVICE_CONTAINER_I): detachable SERVICE_CONTAINER_S do create Result.make (ia_container) end (l_provider)) l_provider.register_with_activator ({detachable SERVICE_PROVIDER_S}, agent (ia_provider: attached SERVICE_PROVIDER_I): detachable SERVICE_PROVIDER_S do create Result.make (ia_provider) end (l_provider)) ensure service_provider_attached: service_provider /= Void end note copyright: "Copyright (c) 1984-2012, Eiffel Software" license: "GPL version 2 (see http://www.eiffel.com/licensing/gpl.txt)" licensing_options: "http://www.eiffel.com/licensing" copying: "[ This file is part of Eiffel Software's Eiffel Development Environment.
