public class PackageNameCheck extends AbstractCheck
Checks that package names conform to a format specified
by the format property. The format is a
regular expression
and defaults to
^[a-z]+(\.[a-zA-Z_][a-zA-Z_0-9_]*)*$.
The default format has been chosen to match the requirements in the Java Language specification and the Sun coding conventions. However both underscores and uppercase letters are rather uncommon, so most projects should probably use ^[a-z]+(\.[a-z][a-z0-9]*)*$.
An example of how to configure the check is:
<module name="PackageName"/>
An example of how to configure the check for package names that begin with
com.puppycrawl.tools.checkstyle is:
<module name="PackageName">
<property name="format"
value="^com\.puppycrawl\.tools\.checkstyle(\.[a-zA-Z_][a-zA-Z_0-9]*)*$"/>
</module>
