com.puppycrawl.tools.checkstyle.checks.indentation.CommentsIndentationCheck

All Implemented Interfaces:

Configurable, Contextualizable

public class CommentsIndentationCheck
extends AbstractCheck

This Check controls the indentation between comments and surrounding code. Comments are indented at the same level as the surrounding code. Detailed info about such convention can be found here

Examples:

To configure the Check:

 
 <module name="CommentsIndentation"/>
 
 
 /*
  * comment
  * some comment
  */
 boolean bool = true; - such comment indentation is ok
    /*
    * comment
    * some comment
     */
 double d = 3.14; - Block Comment has incorrect indentation level 7, expected 4.
 // some comment - comment is ok
 String str = "";
     // some comment Comment has incorrect indentation level 8, expected 4.
 String str1 = "";
