Hello!

I want get File object annotated as Configurable. To do this I wrote this code:

        for(Field field : strategy.getClass().getFields()) {
            for(Annotation annotation : field.getAnnotations()) {
                if(annotation.annotationType().equals(Configurable.class)) {
                    Configurable conf = ((Configurable) annotation);
                    if(conf.value().equals(LOG_FILE_KEY)) {
                        context.getConsole().getOut().println(conf);
                    }
                }
            }
        }

LOG_FILE_KEY - constant name. If we found it in annotations, logging will be forward to this file. If not - just ignore such feature.
Problem is that Configurable not provide any methods to get access to File itself.

Unless you trying to retrieve a @Configurable annotation from another class file, you can use a similar approach to this:

@RequiresFullAccess
public class LoggingToFileStrategy implements IStrategy {
   
   @Configurable("LogFile")
   public File file = new File("C:\\temp\\log.txt");
   
   private IConsole console;
   
   @Override
   public void onStart(IContext context) throws JFException {
      this.console = context.getConsole();

      console.getOut().println("Start, filename: " + this.file.getAbsolutePath());
      String msg = "test message";
      writeToFile(msg);
   }
   
   private void writeToFile(String message) {
      try {
         FileWriter fstream = new FileWriter(this.file);
         fstream.write(message);
         fstream.close();
      } catch (Exception e) {
         console.getOut().println("Error: " + e.getMessage());
      }
   }

I am trying to retrieve File object from another class. Doing this from IStrategy is simple:)

Consider casting the field value:

public File getLogFile() {
   File file = new File("");
   IStrategy strategy = new EmptyStrategy();
   for (Field field : strategy.getClass().getFields()) {
      for (Annotation annotation : field.getAnnotations()) {
         if (annotation.annotationType().equals(Configurable.class)) {
            Configurable conf = ((Configurable) annotation);
            if (conf.value().equals(LOG_FILE_KEY)) {
               try {
                  return (File) field.get(strategy);
               } catch (Exception e) {
                  console.getOut().println(e.getMessage());
               }
            }
         }
      }
   }
   return file;
}
