changing Parameters

Hi,
I'm trying to modify my Parameters using Operator.setParameter(x,y), however I have encountered several problems.
When I change the values of some parameters and run the process, RM throws error, I suggest that change of some parameters prompt change in others. How can I know what is the bond between parameters?

Hi,

there is no "if you change x it will change y". Some parameters depend on others, so y may be hidden while x is false, but in that case y would simply be ignored. You probably put an invalid value into them, like "hello" into a ParameterTypeInt (which of course only accepts integer values).

Hi,
I guess I misinterpreted my problem. What I really want to know is how are parameters of some operators interrelated.For instance, when I change parameter "send_mail" from "never" to "for_long_process" in operator Process (Root operator) two other parameters,the "notification_email" and the "process_duration_for_mail", immediately appear.
I have found something like parametertype.getDependency() but don't really understand how to use it,any suggestion?

Hi,

I think you can try to ask every parameter of an operator via this code fragment if it should be shown everytime you change a parameter.
I haven't done this myself before, so you will have to play around with this a bit.


for (ParameterType type : operator.getParameterTypes()) {
      boolean showParam = true;
      for (ParameterCondition condition : type.getDependencyConditions()) {
             if(!condition.dependencyMet()) {
                     showParam = false;
                     break;
             }
             // your code
       }
}
