public class AvoidInlineConditionalsCheck
extends AbstractCheck

Detects inline conditionals. Here is one example of an inline conditional:

String a = getParameter("a");
String b = (a==null || a.length() > 1) ? null : a.substring(1);

Rationale: Some developers find inline conditionals hard to read, so their employer's coding standards forbid them.
