Member Functions

virtual Sint32 mi::​nservices::​ICommand_response::get_error_code() const [pure virtual]

Returns the error code. see Commands for information on command errors

virtual const char* mi::​nservices::​ICommand_response::get_error_message() const [pure virtual]

Returns the error message, if there is no error returns an empty string.

virtual const IData* mi::​nservices::​ICommand_response::get_extra_error_information() const [pure virtual]

Returns the extra error information, if no extra information returns NULL.

template< class T>

const T* mi::​nservices::​ICommand_response::get_extra_error_information() const [inline]

Returns the extra error information, if no extra information returns NULL. This templated member function is a wrapper of the non-template variant for the user's convenience. It eliminates the need to call mi::base::IInterface::get_interface(const Uuid&) on the returned pointer, since the return type already is a pointer to the type T specified as template parameter.

Returns

The error information.

virtual const ICommand_request* mi::​nservices::​ICommand_response::get_request() const [pure virtual]

Returns the request associated with this response.

Returns

The request, NULL if no request has been associated.

virtual const IData* mi::​nservices::​ICommand_response::get_result() const [pure virtual]

Returns the result of the command Do not rely on the return value of this to indicate success or failure as NULL is a valid result. Use is_error() to determine errors.

Returns

The result.

template< class T>

const T* mi::​nservices::​ICommand_response::get_result() const [inline]

Returns the result of the command Do not rely on the return value of this to indicate success or failure as NULL is a valid result. Use is_error() to determine errors.

Returns

The result.

virtual bool mi::​nservices::​ICommand_response::is_error() const [pure virtual]

Indicates whether an error occurred.

Returns

true if an error occurred

virtual void mi::​nservices::​ICommand_response::set_error( Sint32 code, const char* message, const IData* extra_information = NULL) [pure virtual]

Flag that an error has occurred. see Commands for information on command errors

Parameters

code

the error code

message

the error message

extra_information

Optional argument containing additional error information.

virtual void mi::​nservices::​ICommand_response::set_result( const IData* value) [pure virtual]

Sets the result of the command.

Note:

• If value was created as a consequence of an mi::neuraylib::ITransaction::edit() or mi::neuraylib::ITransaction::access() call then that transaction must still be open otherwise it may not be possible to retrieve the result.

• All values passed in are deep copied internally. Additionally, any mi::IPointer or mi::IConst_pointer types found will be automatically dereferenced. Finally, mi::IRef types will be converted to an mi::IString containing the name of the database element referenced.

Parameters

value

the result. NULL is valid.
