Detailed Description

Defines the Profile interface.

An abstract base class for representing object location information. This is based on the CORBA IOR definitions.

Constructor & Destructor Documentation

TAO_Profile::TAO_Profile	(	CORBA::ULong	tag,
		TAO_ORB_Core *	orb_core,
		const TAO_GIOP_Message_Version &	version
	)

Constructor.

TAO_Profile::~TAO_Profile ( void ) [protected, virtual]

If you have a virtual method you need a virtual dtor.

TAO_Profile::TAO_Profile	(	CORBA::ULong	tag,
		TAO_ORB_Core *	orb_core,
		const TAO::ObjectKey &	key,
		const TAO_GIOP_Message_Version &	version
	)		`[protected]`

To be used by inherited classes.

TAO_Profile::TAO_Profile ( const TAO_Profile & ) [private]

Member Function Documentation

unsigned long TAO_Profile::_decr_refcnt ( void )

Decrement the object's reference count. When this count goes to 0 this object will be deleted.

unsigned long TAO_Profile::_incr_refcnt ( void )

Increase the reference count by one on this object.

TAO::ObjectKey * TAO_Profile::_key ( void ) const

Obtain the object key, return 0 if the profile cannot be parsed. The memory is owned by the caller!

Reimplemented in TAO_Unknown_Profile.

void TAO_Profile::add_generic_endpoint ( TAO_Endpoint * ep ) [virtual]

Add a protocol-agnostic endpoint.

Reimplemented in TAO_IIOP_Profile.

void TAO_Profile::add_tagged_component ( const IOP::TaggedComponent & component )

Add the given tagged component to the profile.

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.

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.

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.

Reimplemented in TAO_IIOP_Profile.

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

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, and TAO_IIOP_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.

int TAO_Profile::decode ( TAO_InputCDR & cdr ) [virtual]

Initialize this object using the given CDR octet string.

Reimplemented in TAO_Unknown_Profile.

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.

Implemented in TAO_Unknown_Profile, and TAO_IIOP_Profile.

virtual int TAO_Profile::decode_profile ( TAO_InputCDR & cdr ) [protected, pure virtual]

Decode the protocol specific profile details.

Implemented in TAO_Unknown_Profile, and TAO_IIOP_Profile.

virtual CORBA::Boolean TAO_Profile::do_is_equivalent ( const TAO_Profile * other ) [protected, pure virtual]

Profile equivalence template method invoked on subclasses.

TAO_Profile subclasses must implement this template method so that they can apply their own definition of profile equivalence.

Implemented in TAO_Unknown_Profile, and TAO_IIOP_Profile.

int TAO_Profile::encode ( TAO_OutputCDR & stream ) const [virtual]

Encode this profile in a stream, i.e. marshal it.

Reimplemented in TAO_Unknown_Profile.

int TAO_Profile::encode_alternate_endpoints ( void ) [virtual]

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.

Reimplemented in TAO_IIOP_Profile.

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, and TAO_IIOP_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, and TAO_IIOP_Profile.

virtual CORBA::ULong TAO_Profile::endpoint_count ( void ) const [pure virtual]

Return how many endpoints this profile contains.

Implemented in TAO_Unknown_Profile, and TAO_IIOP_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::forward_to ( TAO_MProfile * mprofiles )

Keep a pointer to the forwarded profile.

TAO_MProfile * TAO_Profile::forward_to ( void )

MProfile accessor.

TAO_MProfile * TAO_Profile::forward_to_i ( void ) [private]

This object keeps ownership of this object.

void TAO_Profile::get_policies ( CORBA::PolicyList & policy_list ) [virtual]

Accessor for the client exposed policies of this profile.

virtual CORBA::ULong TAO_Profile::hash ( CORBA::ULong max ) [pure virtual]

Return a hash value for this object.

Implemented in TAO_Unknown_Profile, and TAO_IIOP_Profile.

CORBA::ULong TAO_Profile::hash_service_i ( CORBA::ULong m ) [protected]

CORBA::Boolean TAO_Profile::is_equivalent ( const TAO_Profile * other_profile )

Verify profile equivalance.

Two profiles are equivalent if their tag, object_key, version and all endpoints are the same.

See also:: do_is_equivalent_i(); is_equivalent_hook()

Returns:: true if this profile is equivalent to other_profile.

TAO_Service_Callbacks::Profile_Equivalence TAO_Profile::is_equivalent_hook ( const TAO_Profile * other ) [protected, virtual]

Allow services to apply their own definition of "equivalence.".

This method differs from the do_is_equivalent() template method in that it has a default implementation that may or not be applicable to all TAO_Profile subclasses.

Reimplemented in TAO_Unknown_Profile.

TAO_Endpoint * TAO_Profile::next_filtered_endpoint ( TAO_Endpoint * source )

Return the next filtered endpoint in the list after the one passed in. This method is implemented in terms of TAO_Endpoint;:next_filtered(). If the supplied source endpoint is null, this returns the first filtered endpoint.

const TAO::ObjectKey & TAO_Profile::object_key ( void ) const

Deprecated:: Return a reference to the Object Key.

virtual char TAO_Profile::object_key_delimiter ( void ) const [pure virtual]

The object key delimiter.

Implemented in TAO_Unknown_Profile, and TAO_IIOP_Profile.

void TAO_Profile::operator= ( const TAO_Profile & ) [private]

TAO_ORB_Core * TAO_Profile::orb_core ( void ) const

Get a pointer to the TAO_ORB_Core.

void TAO_Profile::parse_string ( const char * string ) [virtual]

Initialize this object using the given input string. Supports URL style of object references

Reimplemented in TAO_Unknown_Profile.

virtual void TAO_Profile::parse_string_i ( const char * string ) [protected, pure virtual]

Protocol specific implementation of parse_string ()

Implemented in TAO_Unknown_Profile, and TAO_IIOP_Profile.

void TAO_Profile::policies ( CORBA::PolicyList * policy_list ) [virtual]

This method sets the client exposed policies, i.e., the ones propagated in the IOR, for this profile.

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

Reimplemented in TAO_IIOP_Profile.

void TAO_Profile::set_tagged_components ( TAO_OutputCDR & cdr ) [protected]

Helper method that encodes the endpoints for RTCORBA as tagged_components.

Returns true if this profile can specify multicast endpoints.

bool TAO_Profile::supports_non_blocking_oneways ( void ) const [virtual]

Returns true if this profile supports non blocking oneways.

CORBA::ULong TAO_Profile::tag ( void ) const

The tag, each concrete class will have a specific tag value.
