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
