}

For increased flexibility in a real application, you may want to read the XML syntax 
description from a file rather than having it embedded in the Java source code. This 
way, it becomes possible to change the mapping between names and codes without 
recompiling the application.

The 3GPP Rf Interface dictionary is returned by getRfDictionary() and the 3GPP 
Ro

 Interface dictionary is returned by getRoDictionary() and can be extended by 

the Diameter stack.

The DiameterTraceLoggerListener class is an interface to the Diameter tracing 
and logging mechanism. This interface represents the communication channel 
implemented by an application to receive debug traces and logs from the Diameter 
stack implementation. Logs are messages targeted to the user of DiameterStack. 
Traces are for internal use and are meaningful only to people with a good knowledge 
of the DiameterStack implementation.

All the messages that may be sent through the 
DiameterTraceLoggerListener.log()

 logging interface are defined in 

LogMessages.def

. There is no definition file for trace messages.

By default, logs are sent to stdout and traces are not sent. This behavior may be 
modified by users either by registering a user-defined subclass of 
DiameterTraceLoggerListener

 or by defining specific environment variables. An 

example of a DiameterTraceLoggerListener implementation is as follows:

Class MyTraceLoggerListener implements DiameterTraceLoggerListener

{

      // true or false.

      public boolean isTracingEnabled()

      {

         return true;

}

public void log (String file, int line, int severity, String message)

{

         String severity;

         switch (severity) {

            case LOG_INFO_SEVERITY: severity=

"

INFO

"

; break;

            case LOG_WARNING_SEVERITY: severity=

"

WARNING

"

; break;

            case LOG_ERROR_SEVERITY: severity=

"

ERROR

"

; break;

            case LOG_DISASTER_SEVERITY: severity=

"

DISASTER

"

; break;

            default: severity=

"

?

"

; break;

         }
