Non-public:

        <module name="JavadocType">
                      <property name="scope" value="public"/>
        </module>

Inherited:

    Javadoc is not required on a method that is tagged with the @Override annotation. However under Java 5 it is not possible to mark a method required for an interface (this was corrected under Java 6).
    Hence Checkstyle supports using the convention of using a single {@inheritDoc} tag instead of all the other tags.

Classes not mentioned.
However: Even inherited classes could have javadoc - with a summary of in what way it extends or implements it's base or iface.

I don't think its check is adequately configurable or robust.  In 
particular, I think it is OK to omit JavaDoc in the following cases:

* The class or member in question is non-public and not a serializable field
* The documentation may be inherited

I don't think the checkstyle check can be configured to handle this.
