Passing external variables from eclipse [message #1744287]

Hi,

I would like to pass some values into the qvto code from the eclipse. Until this moment, the code .qvto is hard-coded to do some comparatives. Is it possible to do that?

Thanks,

Regards,

Daniel.

Hi

I'm not entirely sure what you mean by "from the eclipse" or "comparatives" but perhaps one of the two observations below may help.

You may define a configuration property in your *.qvto; e.g.

configuration property visitorInterfaceName : String;

UI: You can configure the configuration property on the Configuration tab of the launch configuration.

API: You may use org.eclipse.m2m.qvt.oml.ExecutionContextImpl.setConfigProperty()

Regards

Ed Willink

Hello Ed,

I cannot assign values to variables, according to your explanation. I am doing something wrong or this kind of feature just work in java because you mention to include an import directive.

Here some screenshot of what I did:

Declaration of the configuration property:
index.php/fa/27212/0/

Set de value field in lauch configurations:
index.php/fa/27213/0/

Log instruction and its result:
index.php/fa/27214/0/

Thank you.

Daniel.

The screenshot with Console output clarifies that you use "QVTO Application Launch Delegate" to run the script.
This type of configuration is provided for the case when you simultaneously co-develop Java blackbox and Qvto script which makes calls to it.

For simple cases it's enough to use "Operational QVT Interpreter" to launch scripts.

I've tested both run configurations and it seems that "QVTO Application Launch Delegate" does not correctly pass initial values for configuration properties. I'll check this further.

Sergey.
