public class PackageNameCheck extends AbstractCheck
Checks that package names conform to a format specified by the format property.
The default value of format for module PackageName 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 configurations should probably assign value
^[a-z]+(\.[a-z][a-z0-9]*)*$ to format for module PackageName.
format - Specifies valid identifiers. Default value is
"^[a-z]+(\.[a-zA-Z_][a-zA-Z0-9_]*)*$".
An example of how to configure the check is:
<module name="PackageName"/>
An example of how to configure the check to ensure with packages start with a lowercase letter and only contains lowercase letters or numbers is:
<module name="PackageName">
<property name="format"
value="^[a-z]+(\.[a-z][a-z0-9]*)*$"/>
</module>
