public class GenericIllegalRegexpCheck
extends AbstractFormatCheck

A generic check for code problems, the user can search for any pattern. This is similar to a recursive grep, only that it's integrated in checkstyle.

Rationale: This Check can be used to prototype checks and to find common bad pratice such as calling ex.printStacktrace(), System.out.println(), System.exit(), etc.

An example of how to configure the check for calls to System.out.println is:

 <module name="GenericIllegalRegexp">
    <property name="format" value="System\.out\.println"/>
 </module>
