CORBA26 — Channel Setup for Emits ports.

  • Key: CORBA26-39
  • Legacy Issue Number: 3937
  • Status: closed  
  • Source: Open Networks Engineering ( Jean-Christophe Dubois)
  • Summary:

    I found 2 (possibly) contradictory statement in 99-10-04 for "emits" ports.

    1) in 62.4.1.2 The Event Interface

    EventConsumerBase obtain_channel (in string supp_name, in EventHeader hdr)
    raises (InvalidName);

    The obtain_channel operation is used by the component to obtain an
    EventConsumerBase which it can use to push events. This operation
    corresponds to an emits declaration in component IDL. The supp_name string
    identifies an Interoperable Naming Service (INS) name which is used to
    identify the SupplierAdmin to be used by CORBA notification. The name is
    associated with the SupplierAdmin thorough container specific configuration
    data. The obtain_channel operation may optionally specify the EventHeader
    required by CORBA notification which will be used for all events pushed to
    this channel. If hdr is present, it is prefixed to all events pushed to this
    channel. If not, it is defaulted as described in Section 66.4, "Event
    Management Integration," on page 66-252. If the supp_name is not recognized,
    the InvalidName exception shall be raised.

    2) in 66.4.2 Transmitting an event

    . channel lookup - for emitted events, this is the channel configured for
    general use at container start-up, for published events, this is the channel
    established by the container for the purpose of pushing this event type.

    Section 62.4.1.2 seems to imply that there can be a different event channels
    for each emit port while 66.4.2 seems to imply that there is only one event
    channel shared by all emits ports.

    What means "general use"?

    What is the truth/intent?.

    Could you make things clear?

    I certainly preffer 1)
