RTC Component

As already explained in the design document, RTC Components are software applications that adhere to specific communication, computation and composition principles defined in the RTC Tk Component Model.

The RTC Tk component infrastructure provides libraries that support the simple creation of such RTC Components.

Supported Functionality

Currently the following functionality is supported for each RTC Component out of the box:

Functionality	Description
Component Identity	Component instance name and component version
Component Life-Cycle	Runnable State Machine and interface towards business logic
Command Reception	SVIF and FCIF commands are received via CII MAL Req/Rep
State Publication	State updates are written to OLDB and published via CII MAL Pub/Sub
Logging	Logging is initialised, configured and a default logger is created
Runtime Repository Access	Service Adapter to access the Runtime Configuration Repository
OLDB Access	Service Adapter to access the Online Database
Service Discovery	Service Adapter to access the Service Registry

API Usage

Tutorial Creating a Simple RTC Component explains how to make use of the provided libraries in order to create a simple RTC Component application that runs a user-provided business logic.

Limitations and Known Issues

More advanced functionality such as alternative component life-cycles (e.g. Loop State Machine), user-specific commands and life-cycles, or event interfaces with subscription functionality are not supported yet. Such features will be added in a subsequent release.

Other functionality such as the support of user-defined command line arguments was omitted on purpose to disencourage its use for now. This will be revisited later when the CII Config Service is available and some experience is gained how it can be best integrated.
