com.puppycrawl.tools.checkstyle.checks.whitespace.NoLineWrapCheck

All Implemented Interfaces:

Configurable, Contextualizable

public class NoLineWrapCheck
extends Check

Checks that chosen statements are not line-wrapped. By default this Check restricts wrapping import and package statements, but it's possible to check any statement.

Examples

Examples of line-wrapped statements (bad case):

 package com.puppycrawl.
    tools.checkstyle.checks;

 import com.puppycrawl.tools.
    checkstyle.api.Check;
 

To configure the check to force no line-wrapping in package and import statements (default values):

 <module name="NoLineWrap"/>
 

To configure the check to force no line-wrapping only in import statements:

 <module name="NoLineWrap">
     <property name="tokens" value="IMPORT">
 </module>
 

Examples of not line-wrapped statements (good case):

 import com.puppycrawl.tools.checkstyle.api.Check;
