Is this for the GrGL data types?

[Chris Dalton, 2014/05/30 21:39:41]

Yeah - GrGLuint. Would you prefer to use a more generic type and not need this
header?

[bsalomon, 2014/06/02 15:14:43]

I was mostly just curious. But maybe we could separate out the simple types from
GrGLFunctions.h

+
+/**
+ * This class takes ownership of a range of OpenGL object names and manages
+ * allocations within that range. This allows the app to generate new objects
+ * on the client side without having to make round trips to the GL server.
+ */
+
+class GrGLNameAllocator {
+    class SparseNameRange;

[bsalomon, 2014/05/30 18:09:11]

Can you move these down to the explicit private section?

+    class SparseNameTree;
+    class ContiguousNameRange;
+
+public:
+    GrGLNameAllocator(GrGLuint names, GrGLuint range);
+    ~GrGLNameAllocator();
+
+    GrGLuint names() const { return fNames; }

[bsalomon, 2014/05/30 18:09:11]

some docs here would useful

+    GrGLuint range() const { return fRange; }
+
+    GrGLuint allocateName();
+    void freeName(GrGLuint name);
+
+private:
+    const GrGLuint fNames;
+    const GrGLuint fRange;
+    SkAutoTUnref<SparseNameRange> fAllocatedNames;
+};
+
+#endif
