could do with a better name

[Eric Willigers, 2015/09/14 07:20:24]

Acknowledged. Renamed to InvalidationLists.

+    WTF_MAKE_NONCOPYABLE(InvalidationListData);
+public:
+    static PassOwnPtr<InvalidationListData> create() { return adoptPtr(new InvalidationListData); }
+
+    InvalidationSetVector& descendants() { return m_invalidationList[InvalidateDescendants]; }

This doesn't need an array and an enum like this.

[Eric Willigers, 2015/09/14 07:20:23]

Fixed.

+    InvalidationSetVector& siblings() { return m_invalidationList[InvalidateSiblings]; }
+
+private:
+    InvalidationListData() {}
+
+    InvalidationSetVector m_invalidationList[InvalidateTypeCount];

[esprehn, 2015/09/10 08:54:53]

Please don't use an array of Vectors, this only contains two of them, just add
two InvalidationSetVector's here.

[Eric Willigers, 2015/09/14 07:20:24]

Done.
