Add final.

It somewhat difficult to know whether the class doesn't have subclasses (need to
know all inheritance hierarchy). I'd like to address it later. Added a FIXME
comment.

Makes sense. You don't need to try hard to add final. Simplicity of the IDL
compiler would be more important.

+    ALLOW_ONLY_INLINE_ALLOCATION();
+public:
+    TestDictionaryDerivedImplementedAs();
+
+    bool hasDerivedStringMember() const { return !m_derivedStringMember.isNull(); }
+    String derivedStringMember() const { return m_derivedStringMember; }
+    void setDerivedStringMember(String value) { m_derivedStringMember = value; }
+
+    bool hasDerivedStringMemberWithDefault() const { return !m_derivedStringMemberWithDefault.isNull(); }
+    String derivedStringMemberWithDefault() const { return m_derivedStringMemberWithDefault; }
+    void setDerivedStringMemberWithDefault(String value) { m_derivedStringMemberWithDefault = value; }
+
+    virtual void trace(Visitor*);

Can we add override ?

[bashi, 2014/11/19 11:04:43]

Unfortunately, no. We use the same template for the base class and derived
class.

[haraken, 2014/11/19 11:50:32]

Ditto.

+
+private:
+    String m_derivedStringMember;
+    String m_derivedStringMemberWithDefault;
+
+    friend class V8TestDictionaryDerivedImplementedAs;
+};
+
+} // namespace blink
+
+#endif // TestDictionaryDerivedImplementedAs_h
