Class TOAImpl

  • All Implemented Interfaces:
    TOA, ObjectAdapter, Object

    @ManagedObject
    @Description("The Transient Object Adapter")
    public class TOAImpl
    extends ObjectAdapterBase
    implements TOA
    The Transient Object Adapter (TOA) represents the OA for purely transient objects. It is used for standard RMI-IIOP as well as backwards compatible server support (i.e. the ORB.connect() method) Its characteristics include:
    • There is only one OA instance of the TOA. Its OAId is { "TOA" }
    • There is not adapter manager. The TOA manager ID is fixed.
    • State is the same as ORB state (TBD)
    Other requirements:
    • All object adapters must invoke ORB.adapterCreated when they are created.
    • All adapter managers must invoke ORB.adapterManagerStateChanged when their state changes, mapping the internal state to an ORT state.
    • AdapterStateChanged must be invoked (from somewhere) whenever an adapter state changes that is not due to an adapter manager state change.

      • getLocalServant

        public Object getLocalServant​(byte[] objectId)
        Description copied from interface: ObjectAdapter
        Get the servant corresponding to the given objectId, if this is supported. This method is only used for models where the servant is an ObjectImpl, which allows the servant to be used directly as the stub. This allows an object reference to be replaced by its servant when it is unmarshalled locally. Such objects are not ORB mediated.
        Specified by:
        getLocalServant in interface ObjectAdapter
        Specified by:
        getLocalServant in class ObjectAdapterBase
        Parameters:
        objectId - byte array representing the object ID
        Returns:
        corresponding servant
      • getInvocationServant

        public void getInvocationServant​(OAInvocationInfo info)
        Get the servant for the request given by the parameters. This will update thread Current, so that subsequent calls to returnServant and removeCurrent from the same thread are for the same request.
        Specified by:
        getInvocationServant in interface ObjectAdapter
        Specified by:
        getInvocationServant in class ObjectAdapterBase
        Parameters:
        info - is the request containing the rest of the request
      • getInterfaces

        public java.lang.String[] getInterfaces​(java.lang.Object servant,
                                                byte[] objectId)
        Return the most derived interface for the given servant and objectId.
        Specified by:
        getInterfaces in interface ObjectAdapter
        Specified by:
        getInterfaces in class ObjectAdapterBase
        Parameters:
        servant - servant object
        objectId - byte array forming the objectId
        Returns:
        list of derived interfaces
      • enter

        public void enter()
                   throws OADestroyed
        Description copied from interface: ObjectAdapter
        enter must be called before each request is invoked on a servant.
        Specified by:
        enter in interface ObjectAdapter
        Specified by:
        enter in class ObjectAdapterBase
        Throws:
        OADestroyed - is thrown when an OA has been destroyed, which requires a retry in the case where an AdapterActivator is present.
      • exit

        public void exit()
        Description copied from interface: ObjectAdapter
        exit must be called after each request has been completed. If enter is called and completes normally, there must always be a corresponding exit. If enter throw OADestroyed, exit must NOT be called.
        Specified by:
        exit in interface ObjectAdapter
        Specified by:
        exit in class ObjectAdapterBase
      • connect

        public void connect​(Object objref)
        Description copied from interface: TOA
        Connect the given servant to the ORB by allocating a transient object key and creating an IOR and object reference using the current factory.
        Specified by:
        connect in interface TOA
        Parameters:
        objref - servant to connect to the ORB
      • disconnect

        public void disconnect​(Object objref)
        Description copied from interface: TOA
        Disconnect the object from this ORB.
        Specified by:
        disconnect in interface TOA
        Parameters:
        objref - ORB to disconnect from
