|
|
* @brief A macro that defines motor factory.
|
|
*
|
|
* The factories are registered to the CMotorFactory which uses them to create motors.
|
|
* To define a new type of motor it needs to derive from CMotorBase and be registered.
|
|
*
|
|
* Example usage:
|
|
*
|
|
* \code{.cpp}
|
|
* REGISTER_MOTOR_FACTORY(PCI_8164_ADLINK, CMotor_8164)
|
|
* \endcode
|
|
*
|
|
* @param mType The motor type.
|
|
* @param motor_class The class of the motor that the factory creates.
