The Java CIL provides a different logging facility than the C++ CIL. This gives the customer application 
more flexibility in how trace messages are handled. It also limits the number of special privileges the 
browser would need to give the applet using the CIL; the Java CIL will only need to access the network 
and not the file system. For that reason, the Java CIL does its tracing through the firing of special events 
called “LogEvents” that the custom application can trap and handle in however way it sees fit. 

The Java CIL provides the following objects for logging as part of the utilities package:

This interface must be implemented by a class interested in receiving Java CIL LogEvents. It only has 
one method.

void processLogEvent(LogEvent event)

A custom application that is interested in receiving LogEvents will receive an object of this type 
whenever a log message is generated. This class extends the Java “EventObject”, and has one public 
method:

getDescription

Returns the text description to write somewhere.

String getDescription()

A custom application that is interested in firing or handling its own LogEvents, can create an instance 
of this class.

Logger

Public constructor of the Logger object.

Trace

Lets the custom app fire a LogEvent

GetTraceMask

Gets the trace mask.

IsTraceMaskEnabled

Determines if a certain trace mask is set.

addLogListener

Subscribe to receive LogEvents.

removeLogListener

Unsubscribe from receiving LogEvents.
