void TAO_Profile::addressing_mode ( CORBA::Short  addr_mode  )  [virtual]

Set the addressing mode if a remote servant replies with an addressing mode exception. If this profile doesn't support a particular addressing mode, this method needs to be overridden signal the appropriate error.

** RACE CONDITION NOTE **

Currently, getting and setting the addressing mode is not protected by a mutex. Theoretically, this could cause a race condition if one thread sends a request, then gets an exception from the remote servant to change the addressing mode, and then another thread sends a different request to the same servant using the wrong addressing mode. The result of this is that we'll get another address change exception. (Annoying, but not that bad.)

In practice at the current time, the above theoretical case never happens since the target specification always uses the object key except for MIOP requests. Remote ORBs can't respond to MIOP requests even to send exceptions, so even in this case, the race condition can't happen.

Therefore, for the time being, there is no lock to protect the addressing mode. Given that the addressing mode is checked in the critical path, this decision seems like a good thing.

00607   // ** See race condition note about addressing mode in Profile.h **

CORBA::Short TAO_Profile::addressing_mode ( void   )  const

Return the current addressing mode for this profile. In almost all cases, this is TAO_Target_Specification::Key_Addr.

Definition at line 56 of file Profile.inl.

00057 {
00058   return this->addressing_mode_;
00059 }

TAO_Endpoint * TAO_Profile::base_endpoint ( void   )  [virtual]

Return a pointer to this profile's endpoint. If the most derived profile type uses an endpoint that is a type that does not derive from the endpoint type of the base profile, then this method returns the base type's endpoint. For example, SSLIOP_Profile derives from IIOP_Profile, but SSLIOP_Endpoint does not derive from IIOP_Endpoint. Because SSLIOP is tagged the same as IIOP, this method is required to facilitate the Endpoint Policy's filtering function. The default implementation of base_endpoint simply returns endpoint.

00103 {
00104   return this->endpoint();
00105 }

CORBA::Boolean TAO_Profile::compare_key ( const TAO_Profile other  )  const

Compare the object key for this profile with that of another. This is weaker than is_equivalent

00706 }

virtual void TAO_Profile::create_profile_body ( TAO_OutputCDR cdr  )  const [protected, pure virtual]

Creates an encapsulation of the ProfileBody struct in the cdr.

Implemented in TAO_Unknown_Profile.

IOP::TaggedProfile * TAO_Profile::create_tagged_profile ( void   ) 

This method is used to get the IOP::TaggedProfile. The profile information that is received from the server side would have already been decoded. So this method will just make a IOP::TaggedProfile struct from the existing information and return the reference to that. This method is necessary for GIOP 1.2.

virtual int TAO_Profile::decode_endpoints ( void   )  [protected, pure virtual]

Helper for decode(). Decodes endpoints from a tagged component. Decode only if RTCORBA is enabled. Furthermore, we may not find TAO_TAG_ENDPOINTS component, e.g., if we are talking to nonRT version of TAO or some other ORB. This is not an error, and we must proceed. Return 0 on success and -1 on failure.

Encodes this profile's endpoints into protocol specific tagged components. This is used for non-RTCORBA applications that share endpoints on profiles. The only known implementation is IIOP, using TAG_ALTERNATE_IIOP_ADDRESS components.

virtual int TAO_Profile::encode_endpoints ( void   )  [pure virtual]

Encodes this profile's endpoints into a tagged component. This is done only if RTCORBA is enabled, since currently this is the only case when we have more than one endpoint per profile.

Implemented in TAO_Unknown_Profile.

virtual TAO_Endpoint* TAO_Profile::endpoint ( void   )  [pure virtual]

Return a pointer to this profile's endpoint. If the profile contains more than one endpoint, i.e., a list, the method returns the head of the list.

Implemented in TAO_Unknown_Profile.

Return how many endpoints this profile contains.

Implemented in TAO_Unknown_Profile.

TAO_Endpoint * TAO_Profile::first_filtered_endpoint ( void   ) 

Return the first endpoint in the list that matches some filtering constraint, such as IPv6 compatibility for IIOP endpoints. This method is implemented in terms of TAO_Endpoint::next_filtered().

void TAO_Profile::remove_generic_endpoint ( TAO_Endpoint ep  )  [virtual]

Remove the provided endpoint from the profile. Some subclasses of TAO_Profile already have a protocol-specific version of remove_endpoint, but this generic interface is required. The default implementation is a no-op. Protocol maintainers wishing to add support for the EndpointPolicy must implement remove_generic_endpoint to call their protocol-specific version of remove_endpoint
