Detailed Description

Virtual base class to define the interface for event io.

Sensor and Actuator event IO

A vDevice provides an virtual interface to execute actuator events and sense sensor events, ie ReadSensor() and WriteActuator(). The latter is prepared to be organized as a background thread that accumulates events in an internal fifo buffer. Once a sensor event has been read by the application, the buffer is cleared. A device is configured by passing an event set with device event attributes. The virtual base class formalls takes void attributes, and uses a dynamic cast to the actual attribute type that is provided by any derived class.

Physical Time

The vDevice defines an interface to access the current physical time. The default implementation has msec resolution and is based on the system clock. Time may be queried in ms by CurrentTimeMs() or in faudes time unis (ftu) by CurrentTime(). Faudes time units refer to defining data in eg guards and invariants of timed automata or stochastical execution properties. Conversion to physical time is by the factor mTimeScale given in msecs per ftu. There is also a default implementation WaitSensors() for timed waiting for events based on pthread conditions. This requires a derived class to send the according pthread signal. Both, physical time and waiting for events, may be overwritten in derived classes.

Operating Status

The device may be in one of four operating states Down, StartUp, Up or ShutDown. Once configured you may Start() the device. The device will assychonously allocate required resources and if successful eventually be in state Up. While the device is Up, you can write actuators and read events. You can request the device to release resources by calling Stop(). While Up, you may also Reset() the device, to set actuators in passive state, to reset physical time to zero and tu flush the sensor fifo buffer.

File IO

The vDevice provides std faudes token io interface via faudes::Type. In addition, there is a static constructor FromTokenreader() to construct a vDevice object of specific type as indentifies by the token section.

Token output, see Type::Write for public wrappers.

The vDevice inplements token writing to consist of DoWritePreface (device name and time scale). and DoWriteConfiguration (device specific event attributes). The default label is taken from the member variable mDefaultLabel. Derived classes are meant to set mDefaultLabel in their constructor and to reimplement DoWritePreface to add additional data eg cycle time or network address. The parameter pContext is ignored and passed on.

Parameters:
rTw Reference to TokenWriter
rLabel Label of section to write, defaults to name of set
pContext Write context to provide contextual information

Reimplemented from faudes::Type.

Writes non-event-configuration data from TokenWriter.

This function is part of the non-event-configuration token-output mechanism. The vDevice will write its name and the time scale, derived classes are meant to first call the base class method and then add additional configuration parameter.

Note: in order to keep the inputfile-layout as easy as possible no label will be used to separate this data-section. Never the less a default-label ("Device") is specified.
