Hi,

I have an interface that looks like this:

/**
 * @author eraonel
 *
 */
public interface IConstraint {
   
    /** Method for validation of a specific constraint */
    void validate (MomDataReader mdr);
   
   
}

All XXconstraint classes implement this interface.

In one XXconstraint class I have the following impl. of validate ( see
below).

I only want to print the Ok! lines when I have debug on.
Errors shall always be printed and nicely written to file.
When a precondition is not fullfilled then I want to throw a
ValidateException(String msg).

What is a good way to approach this matter?
All design hints are welcome.

cheers,

//validate
public void validate(MomDataReader mdr){
   
        // get all actions in the mon
        MomClass [] clazzes = mdr.getAllClasses();
        for (int i = 0; i < clazzes.length; i++) {   
            MomClass clazz = clazzes[i];
            MomAction[] actions = clazz.getAllActions();
            if (actions != null) {
                for (int j = 0; j < actions.length; j++) {
                    MomAction action = actions[j];
                    String actionName = action.getName();
                    if(actionName.matches("[a-z][]A-Za-z0-9]*")){
//Ok!                        System.out.println("Class: "+clazz.getName()+" action :
"+actionName+"Ok!");
                    }else{
                       
//Error                        System.out.println("Class: "+clazz.getName()+" action :
"+actionName+"Error!");
                       
                    }
                }

            } else {//Precondition not fullfilled to validate
                System.out.println("No actions for Class: "+clazz.getName());
            }
        }
       
    }
