Marshalling for a service

Submitted by alainscialoja on Mon, 2013-04-29 17:44

Hi all,
I'm a student working on a thesis on iTaSC. I have a question:
I created a service plugin (cpp) to monitor the output of a component. This service has many properties. I would like to add the marshalling service to my service but I can't figure out how to do this.
I included "#include <rtt/marsh/Marshalling.hp

" and used
"boost::shared_ptr<Marshalling> Marshalling = this->getProvider<RTT::Marshalling>("marshalling");" but I get:
"error: ‘class "class_name"’ has no member named ‘getProvider’".

I know getProvider is a method of the class "RTT::TaskContext" and I guess I shouldn't inherit this class in a service. Is there a way to use marshaling in a service? Should I create a component instead?

Best regards,
Alain

Hi Alain,

Use the PropertyLoader class directly. It is quite easy to use and works
also for properties of services.

Thank you Peter, The PropertyLoader worked like a charm. I used: 

#include <rtt/marsh/PropertyLoader.hpp>
...
PropertyLoader pl(this);
pl.load("cpf/"conFile.cpf")
