Doxygen graphs incomplete?

Hi,

UnaryOperator is not in the graph on this page, while BinaryOperator is:

   http://clang.llvm.org/doxygen/classclang_1_1Stmt.html

Any idea why?

Regards,
John.

Because Expr has many children, and doxygen has chosen only a subset
of them to show in the graph. This is why the Expr node in the graph
is red, which means "click me to go to my page so that you can see my
full class hierarchy".
