public class SWInterpreter

extends Object

This class is intended to help developers translate from status words returned by a Java Powered iButton into a meaningful message. Normal program execution with the Java Powered iButton is performed using APDU classes and OneWireContainer16, and looks something like this:

       //CommandAPDU capdu already defined
       ResponseAPDU response;        
       response = owc16.sendAPDU(capdu);
       int statusword = response.getSW();
       //use the SWInterpreter class to print a message
       System.out.println(SWInterpreter.interpret(statusword));
 

This class allows you to use the statusword to print a message. If the status word returned was 0x6400, indicating not enough memory, the above code would print the message:

       "SW 0x6400 Insufficient Memory"
