Detailed Description


CORBA2-specified exception hierarchy. All exceptions have a type (represented by a TypeCode) and a widely scoped type ID (in the TypeCode) that are generated by any OMG-IDL compiler and available through the Interface Repository. Think of it as a "globally scoped" name distinguishing each exception.

According to the OMG CORBA C++ Mapping version 1.1, the copy constructors should be moved to "protected" section in class declarations. Since the current MS Visual C++ 7.1 compiler will cause some problems to TAO's exception mechanism, we defer doing this until we drop support for MSVC++ 7.1. Maybe there is another solution, have to test that later.

Constructor & Destructor Documentation

CORBA::Exception::Exception ( const Exception src)

Copy constructor.

This constructor should be protected, but VC7.1 at warning level 4 complains about the inaccessible copy constructor preventing it from being caught. However, that probably isn't true for most cases since CORBA exceptions are typically caught by reference, not by copy.
CORBA::Exception::~Exception ( void  )


CORBA::Exception::Exception ( void  )

Default constructor.

CORBA::Exception::Exception ( const char *  repository_id,
const char *  local_name 

Construct from a repository id.

Member Function Documentation

CORBA::Exception * CORBA::Exception::_downcast ( CORBA::Exception x)
CORBA::Exception const * CORBA::Exception::_downcast ( CORBA::Exception const *  x)
virtual ACE_CString CORBA::Exception::_info ( void  ) const
pure virtual

Returns a string containing information about the exception. This function is not CORBA compliant.

Implemented in CORBA::SystemException, and CORBA::UserException.

const char * CORBA::Exception::_name ( void  ) const

Return the name of the Exception.

virtual void CORBA::Exception::_raise ( void  ) const
pure virtual
const char * CORBA::Exception::_rep_id ( void  ) const

Return the repository ID of the Exception.

void CORBA::Exception::_tao_any_destructor ( void *  x)

Used in the non-copying Any insertion operator.

virtual void CORBA::Exception::_tao_decode ( TAO_InputCDR cdr)
pure virtual
virtual CORBA::Exception* CORBA::Exception::_tao_duplicate ( void  ) const
pure virtual

Deep copy.

The following operation is used in the implementation of it performs a deep copy of the exception, normally it is implemented as:

class SomeException : public // Derives from CORBA::Exception
  virtual CORBA::Exception *_tao_duplicate (void) const
    CORBA::Exception *result = 0;
        SomeException (*this),
    return result;

Implemented in CORBA::ORB::InvalidName, CORBA::SystemException, and CORBA::WrongTransaction.

virtual void CORBA::Exception::_tao_encode ( TAO_OutputCDR cdr) const
pure virtual
void CORBA::Exception::_tao_print_exception ( const char *  info,
FILE *  f = stdout 
) const

Print the exception to output determined by f.

This method is TAO-specific.
virtual CORBA::TypeCode_ptr CORBA::Exception::_tao_type ( void  ) const
pure virtual

Will be overridden in the concrete derived classes.

Implemented in CORBA::WrongTransaction, and CORBA::UserException.

CORBA::Exception & CORBA::Exception::operator= ( const Exception src)

Assignment operator.
