List<StringValue> liSVs = params.getValues([Param name]);
if ((liSVs != null) && !liSVs.isEmpty())
{
StringValue svValue = liSVs.get(0);
String sValue = svValue.toOptionalString();
...
}
you can just do
if(params.getNamedKeys().contains("parameter_name"))
{
String svValue = params.get(parameter_name)
String sValue = svValue.toOptionalString();
if(!Strings.isEmpty(sValue)){
--your code--
}
}
