This class is base for parameters of selection operation. 
<p>
This class has no built-in synchronizator, so <code>LOCK_OBJECT</code> and <code>LOCK_THIS_OBJECT</code> macros cannot be used with instances of this class. No public or private methods are thread-safe. <hr><h2>Constructor &amp; Destructor Documentation</h2>
