What's this class for? It doesn't seem to be used for anything.

[anthonyhkf, 2016/07/07 08:01:45]

Done.

This can be on the previous line (blink doesn't have line length limits- see
also the style guide: https://www.chromium.org/blink/coding-style)

[anthonyhkf, 2016/07/07 08:01:45]

Done.

[meade_UTC10, 2016/07/07 05:48:02]

Can this be renamed to referenceAtIndex or something else more descriptive?
(componentAtIndex was used in CSSTransformValue because it contains
CSSTransformComponents, aka components, so you shouldn't keep that name.)

[anthonyhkf, 2016/07/07 08:01:45]

Done.

+    Vector<String> listOfReferences() const { return m_listOfReferences; }

[meade_UTC10, 2016/07/07 05:48:02]

Is this function used anywhere?

[anthonyhkf, 2016/07/07 08:01:45]

Done.

[meade_UTC10, 2016/07/07 05:48:02]

Constructor line breaking should be like this:

MyClass::MyClass(Document* doc)
    : MySuperClass()
    , m_myMember(0)
    , m_doc(doc)
{
}
