  • Summary:

    Document ptc/2001-11-03, CORBA Component Model
    ----------------------------------------------
    62.4.1.1 The CCM2Context Interface
    ....
    local interface CCM2Context : CCMContext

    { HomeRegistration get_home_registration (); void req_passivate () raises (PolicyMismatch); CatalogBase get_persistence (in _TypeId catalog_type_id) raises (PersistenceNotAvailable); }

    ;

    ....
    req_passivate
    The req_passivate operation is used by the component to inform the container
    that it wishes to be passivated when its current operation completes. To be
    valid, the component must have a servant lifetime policy of component or
    container. If not, the PolicyMismatch exception shall be raised.
    ----------------------------------------------

    What happens if req_passivate() operation is not called in the scope of a
    callback operation?
    I think that req_passivate() can only make sense if called in the context of
    a callback operation. The IllegalState exception is appropriate for this
    case.

    The IDL might then look like this :
    void req_passivate () raises (IllegalState,PolicyMismatch);

    and the following sentence might be appended to the paragraph above:
    "If this operation is issued outside of the scope of a callback operation,
    the IllegalState exception is returned."

    This addition will ease implementation of CCM2Context objects based on
    POACurrent : implementing container and component servant lifetime policies
    on a POA with RETAIN servant retention policy and the other servant lifetime
    policies on a POA with NON_RETAIN servant retention policy can rely entirely
    on the POACurrent.
