 21  
  * - a single member of a class.<br><br>
 22  
  * Constraints are constructed by calling 
 23  
  * <a href="Query.html#constrain(java.lang.object)">
 24  
  * <code>Query.constrain()</code></a>.
 25  
  * <br><br>
 26  
  * Constraints can be joined with the methods and() and or().<br><br>
 27  
  * The following mutual exclusive functions set the evaluation mode.
 28  
  * The subsequent call prevails:<br>
 29  
  * identity(), equal(), greater(), greaterOrEqual(), smaller(), 
 30  
  * smallerOrEqual(), like(), contains()<br><br>
 31  
  * is(), and not() are also mutually exclusive.<br><br>
