Description:
------------
The documentation for some iterators does not contain all implemented methods. For example, the documentation for the following iterators do not include the valid() method, which is a required part of the Iterator interface:

- GlobIterator
- ParentIterator
- RecursiveCallbackFilterIterator
- RecursiveDirectoryIterator
- RecursiveRegexIterator
- RegexIterator
- RecursiveDirectoryIterator

I think I see the problem. We only list inherited methods for one level of the inheritance tree. 

Take, for example, GlobIterator. We show its methods, and under "Inherited Methods" we list the methods its parent class (FilesystemIterator) implements.

We currently do not list methods inherited from grandparent classes. In this case, that would be DirectoryIterator, which is where the valid() method is implemented.

Perhaps we should convert this ticket to a feature request to list all inherited methods on each class's synopsis page.

Re-assigning to me to keep visibility.

A complication is that there are many methods defined both in the parent and the grandparent, e.g. DirectoryIterator::current and FilesystemIterator::current.

Just including the grandparent (<xi:include xpointer="xmlns(db=http://docbook.org/ns/docbook) xpointer(id('class.filesystemiterator')/db:refentry/db:refsect1[@role='description']/descendant::db:methodsynopsis[1])" />) would list these methods twice.
