How to check whether a specific argument is present in the argument list..?

[Anon Anon]

In one of my scenarios, I came accross with a situation, where I need to look for a specific argument; say "CountryCode", if it is present, I need to create the responses with the values of the argument.

I did something like this

 

 

import com.itko.lisa.vse.stateful.model.Request;

import com.itko.util.ParameterList;

Request req = (Request) testExec.getStateValue("lisa.vse.request");

String opName = req.getOperation();

ParameterList args = req.getArguments();

String country= args.get("CountryCode");

IF country is USA THEN

ELSE

END

 

However, It is possible that the incoming request is doesnot contain that specific tag, In that scenario, the above code snippet may throw an exception. Please let me know how can I handle this exception and check whether "args" has my specific tag without an exeception..?

Just in case someone else may be looking for an answer to this question; a possible approach could be to do the following:

ParameterList args = lisa_vse_request.getArguments();
Parameter thisParameter;

if(args.toString().contains("CountryCode"))
{
    _logger.info("Great this incoming request does contain CountryCode");

     for(i=0; i<args.size(); i++)
     {
          thisParameter = args.get(i);
          if(thisParameter.getName().equals("CountryCode") && thisParameter.getValue.equals("USA"))
          {
                _logger.info("yep, we've found it..... CountryCode is USA");
          }
     }
else   
   _logger.info("Sorry, this incoming request does NOT contain CountryCode");

Hi Anon, 

You can also use the filter to extract the value and put an assertion around it.

Thanks
