 /**
 26  
  * Detects inline conditionals.
 27  
  *
 28  
  * An example inline conditional is this:
 29  
  * <pre>
 30  
  * String a = getParameter("a");
 31  
  * String b = (a==null || a.length&lt;1) ? null : a.substring(1);
 32  
  * </pre>
 33  
  *
 34  
  * Rationale: Some developers find inline conditionals hard to read,
 35  
  * so their company's coding standards forbids them.
