com.puppycrawl.tools.checkstyle.checks.NewlineAtEndOfFileCheck

All Implemented Interfaces:

Configurable, Contextualizable, FileSetCheck

public class NewlineAtEndOfFileCheck
extends AbstractFileSetCheck

Checks that there is a newline at the end of each file.

An example of how to configure the check is:

 <module name="NewlineAtEndOfFile"/>

This will check against the platform-specific default line separator.

It is also possible to enforce the use of a specific line-separator across platforms, with the 'lineSeparator' property:

 <module name="NewlineAtEndOfFile">
   <property name="lineSeparator" value="lf"/>
 </module>

Valid values for the 'lineSeparator' property are 'system' (system default), 'crlf' (windows), 'cr' (mac) and 'lf' (unix).
