## 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_BEGIN_VERSIONED_NAMESPACE_DECL 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

CORBA::ULong TAO_Profile::_decr_refcnt | ( | void |  | ) |

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

CORBA::ULong 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_tagged_component | ( | const IOP::TaggedComponent & | component | ) |

Add the given tagged component to the profile.

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.

ACE_INLINE 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.

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_IIOP_Profile, and 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.

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_IIOP_Profile, and TAO_Unknown_Profile.

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

Decode the protocol specific profile details.

Implemented in TAO_IIOP_Profile, and TAO_Unknown_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_IIOP_Profile, and TAO_Unknown_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_IIOP_Profile, and TAO_Unknown_Profile.

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

Return 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_IIOP_Profile, and TAO_Unknown_Profile.

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

Return how many endpoints this profile contains.

Implemented in TAO_IIOP_Profile, and TAO_Unknown_Profile.

ACE_INLINE TAO_MProfile * TAO_Profile::forward_to | ( | void |  | ) |

MProfile accessor.

ACE_INLINE void TAO_Profile::forward_to | ( | TAO_MProfile * | mprofiles | ) |

Keep a pointer to the forwarded profile.

ACE_INLINE 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_IIOP_Profile, and TAO_Unknown_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.

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

Deprecated:
  Return a reference to the Object Key.

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

Helper method that encodes the endpoints for RTCORBA as tagged_components.
