| [etrice-dev] Actor Attribute and message data with the same name |
Hi all, I am working with C and I saw the following “problem”: If an Actor has an Attribute like: Structure { external Port ControlPort SAP timer: PTimer Attribute id: uint16 Attribute data:MyDataClass And a receiving message has a parameter (which is defined in the protocol) like: ProtocolClass PButtonController { incoming { Message setId(data: uint16) } outgoing { Message pressed() The C Code generator produces the following output: /* Action Codes */ static void action_TRANS_tr0_FROM_waitForId_TO_released_BY_setIdControlPort(ButtonController* self, InterfaceItemBase ifitem, uint16 data) { self->id=self->data; PTimerConjPort_startTimeout(&self->constData->timer, 50); } In this case „data“ will be interpreted as the Attribute and you can never access the parameter which is sent to actor. This is not a major problem but could be avoided by defining a keyword for the parameter which is sent via a message. In this case it would no longer be necessary (possible) to define your own name for a message data. You would access the received data always via the defined keyword (which is nothing more than a fixed name for the message data). The problem with the current solution is that you may use the same Protocol class at several ActorClasses. Can we solve this by using the action language??? If not, do you think we should change that??
