 /**
 25  
  * <p>
 26  
  * Checks that switch statement has &quot;default&quot; clause.
 27  
  * </p>
 28  
  * <p>
 29  
  * Rationale: It's usually a good idea to introduce a
 30  
  * default case in every switch statement. Even if
 31  
  * the developer is sure that all currently possible
 32  
  * cases are covered, this should be expressed in the
 33  
  * default branch, e.g. by using an assertion. This way
 34  
  * the code is protected aginst later changes, e.g.
 35  
  * introduction of new types in an enumeration type.
 36  
  * </p>
 37  
  * <p>
 38  
  * An example of how to configure the check is:
 39  
  * </p>
 40  
  * <pre>
 41  
  * &lt;module name="MissingSwitchDefault"/&gt;
 42  
  * </pre>
