SmartSoft / CORBA next release

Dear all,

The next release of the SmartSoft / CORBA communication patterns is now
available at the usual web site:

http://www1.faw.uni-ulm.de/orocos/

It now contains a "wiring pattern" which supports dynamic wiring of
components at run time. "Wiring" describes the mechanism to connect the
clients of services to appropriate server components. Dynamic wiring
allows to configure the communication paths between components at run
time. This pattern is e.g. needed when one wants to compose components
context dependent to different behaviors (e.g. connect either the path
planner or the object tracker to the motion control). Typically this job
is done by a sequencing mechanism in robotics which can now use a
standardized wiring service. The extensions are so far included into the
"send" and the "query" pattern. The other communication patterns are
extended very soon.

The pattern itself is based on the query pattern. Clients of services
can now become named ports. These ports can be accessed from outside by
other components and can be connected to any component providing the
appropriate server for the required service. Example components
(smartExampleComponent101/102/103/104) demonstrate the usage of the
wiring pattern.

Dynamic wiring is possible with the previous releases of the
communication patterns, too, but has to be handled individually. The
extensions provide a consistent way to handle dynamic server connections
and therefore simplify dynamic server connections.


Kind regards

Christian Schlegel
