/**
 * SessionLog is the ever-so-simple interface used by
 * EclipseLink to log generated messages and SQL. An implementor of
 * this interface can be passed to the EclipseLink session
 * (via the #setSessionLog(SessionLog) method); and
 * all logging data will be passed through to the implementor
 * via an instance of SessionLogEntry. This can be used
 * to supplement debugging; or the entries could be stored
 * in a database instead of logged to System.out, etc.
 * 
 * This class defines EclipseLink logging levels (that are used throughout EclipseLink code) with the following integer values:
 * 
 * 
 * 
 * 
 * 
 * 
 * 
 * 
 * 
 * 
 *

  INFO      = {@value #INFO}
  WARNING   = {@value #WARNING}
  SEVERE    = {@value #SEVERE}
  OFF       = {@value #OFF}
 * 
 * In addition, EclipseLink categories used for logging name space are defined with the following String values:
 *
