Detailed Description

A TAO_Profile class to handle foreign profiles.

The CORBA spec implies that ORBs must be prepared to save and pass around profiles for protocols it does not recognize. It is not mandatory to *use* those profiles but they shouldn't be dropped. This class stores the information required to marshal and demarshal an unknown profile, but simply returns an error if any of the TAO internal methods are invoked.

Member Function Documentation

TAO::ObjectKey * TAO_Unknown_Profile::_key (  void   )  const [virtual]
 

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

Reimplemented from TAO_Profile.

Definition at line 888 of file Profile.cpp. 

00889 {
00890   return 0;
00891 }

void TAO_Unknown_Profile::create_profile_body (  TAO_OutputCDR &  encap  )  const [private, virtual]
 

Creates an encapsulation of the ProfileBody struct in the cdr.

Implements TAO_Profile.

Definition at line 921 of file Profile.cpp. 

00922 {
00923   // No idea about the profile body! Just return
00924   return;
00925 }

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

Initialize this object using the given CDR octet string.

Reimplemented from TAO_Profile.

Definition at line 852 of file Profile.cpp.

References body_. 

00853 {
00854   if ((cdr >> this->body_) == 0)
00855     {
00856       return -1;
00857     }
00858 
00859   return 0;
00860 }

int TAO_Unknown_Profile::decode_endpoints (  void   )  [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.

Implements TAO_Profile.

Definition at line 869 of file Profile.cpp. 

00870 {
00871   return 0;
00872 }

int TAO_Unknown_Profile::decode_profile (  TAO_InputCDR &  cdr  )  [virtual]
 

Decode the protocol specific profile details.

Implements TAO_Profile.

Definition at line 863 of file Profile.cpp. 

00864 {
00865   return 0;
00866 }

CORBA::Boolean TAO_Unknown_Profile::do_is_equivalent (  const TAO_Profile *  other_profile  )  [protected, 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.

Implements TAO_Profile.

Definition at line 894 of file Profile.cpp.

References body_. 

00895 {
00896   const TAO_Unknown_Profile * op =

00900 }

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

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

Reimplemented from TAO_Profile.

00876 {
00877   stream.write_ulong (this->tag ());
00878   return (stream << this->body_);
00879 }

int TAO_Unknown_Profile::encode_endpoints (  void   )  [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.

Implements TAO_Profile.

Definition at line 882 of file Profile.cpp. 

00883 {
00884   return 0;
00885 }

TAO_Endpoint * TAO_Unknown_Profile::endpoint (  void   )  [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.

Implements TAO_Profile.

Definition at line 815 of file Profile.cpp. 

00816 {
00817   return 0;
00818 }

CORBA::ULong TAO_Unknown_Profile::endpoint_count (  void   )  const [virtual]
 

Return how many endpoints this profile contains.

Implements TAO_Profile.

00822 {
00823   return 0;
00824 }

CORBA::ULong TAO_Unknown_Profile::hash (  CORBA::ULong  max  )  [virtual]
 

Return a hash value for this object.

TAO_Service_Callbacks::Profile_Equivalence TAO_Unknown_Profile::is_equivalent_hook (  const TAO_Profile *  other_profile  )  [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 from TAO_Profile.

Definition at line 903 of file Profile.cpp. 

00904 {

char TAO_Unknown_Profile::object_key_delimiter (  void   )  const [virtual]
