Why is the functor called COMPARE instead of LT or COMPARE_LT?

[bsalomon, 2013/02/27 16:56:36]

Done, and made the comment a bit more explicit about what this is doing.

+template <typename T, int (COMPARE)(const T*, const T*)>
+class SkTSearchCompareFunctor {
+public:
+    bool operator()(const T& a, const T& b) {
+        return COMPARE(&a, &b) < 0;
+    }
+};
