The com.informix.udr.UDRLog

Note: UDRLog is deprecated. It is recommended you use the SLF4J API to log messages for your application. See Traceable Events for more information.
The UDRLog interface provides a simple logging facility for a UDR. The UDRLog interface is defined as follows: 
public interface UDRLog
{
   void log(String msg);
}

The interface defines a single method, log(), which takes a String argument and appends it to the JVP log file, which the JVPLOGFILE configuration parameter specifies.
