Member Functions

virtual const IData* mi::​nservices::​ICommand_request::get_argument( const char* name) const [pure virtual]

Gets the value for argument called name. If returns NULL then this either indicates that the argument name does not exist or that it's value has been supplied as NULL. Currently you would need to use the iterative version of get_argument to distinguish the two conditions.

Parameters

name
the argument name.

Returns

the value.

template< class T>

const T* mi::​nservices::​ICommand_request::get_argument( const char* name) const [inline]

Gets the value for argument called name. If returns NULL then this either indicates that the argument name does not exist or that it's value has been supplied as NULL. Currently you would need to use the iterative version of get_argument to distinguish the two conditions.

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.

Parameters

name
the argument name

Returns

the value or NULL if the argument doesn't exists or is not of type T.

virtual Sint32 mi::​nservices::​ICommand_request::get_argument( Uint32 index, const char** name, const IData** value) const [pure virtual]

Gets the argument name and value at index.

Parameters

index
the index of the argument, start at 0 and increment until returns false
name
receives the name of the argument
value
receives the value of the argument

Returns

  • NRS_ERROR_NONE success, name and value contains the argument name and it's value.
  • NRS_ERROR_NOT_FOUND index is greater than the number of supplied arguments.
  • NRS_ERROR_FAILED general error
virtual IMap* mi::​nservices::​ICommand_request::get_attachments() const [pure virtual]

retrieves the attachment object for this command request

Returns

An object with which to manipulate attachments

virtual const char* mi::​nservices::​ICommand_request::get_command_name() const [pure virtual]

the name of the command to be executed

Returns

the command name

virtual Uint32 mi::​nservices::​ICommand_request::get_num_arguments() const [pure virtual]

the number of arguments to the command

Returns

number of arguments

virtual Sint32 mi::​nservices::​ICommand_request::set_argument( const char* name, const IData* value) [pure virtual]

Sets an argument to the command.

Parameters

name
the name of the argument
value
the argument's value, NULL is a valid value

Returns

  • NRS_ERROR_NONE success.
  • NRS_ERROR_INVALID_PARAMETERS name is NULL or an empty string.
virtual void mi::​nservices::​ICommand_request::set_command_name( const char* command) [pure virtual]

Sets the name of the command to execute.

Parameters

command
the command name
