The usage itself actually is pretty straight forward as you can see.
Just instantiate a
ILog
instance via a static factory method provided by
LogFactory.
After that you are able to invoke the debug methods and pass it a message string and an optional error.
public class MyClass
{
private static const LOG:ILog = LogFactory.getLog(MyClass);
public function MyClass()
{
LOG.debug("created new MyClass instance");
}
}
