Class AvoidInlineConditionalsCheck

  • All Implemented Interfaces:
    Configurable, Contextualizable
    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.

    To configure the check: 

     <module name="AvoidInlineConditionals"/>

    Example:

     int x = 5;
 boolean foobar = (x == 5); // OK

 String text;
 text = (text == null) ? "" : text; // violation

 String b;
 if (a != null && a.length() >= 1) { // OK
   b = a.substring(1);
 } else {
   b = null;
 }

 b = (a != null && a.length() >= 1) ? a.substring(1) : null; // violation
