-#include "base/values.h"

[Lei Zhang, 2010/08/05 19:00:18]

I'm removing unneeded headers one header at a time - i.e. look over all
#includes of base/values.h. I guess we'll conflict a bit here.

-#include "chrome/browser/bookmarks/bookmark_model.h"
+#include <string>
+
+#include "base/basictypes.h"
+
+class BookmarkModel;
+class BookmarkNode;
+class DictionaryValue;
+class ListValue;
 
 // Helper functions.
 namespace extension_bookmark_helpers {
 
 DictionaryValue* GetNodeDictionary(const BookmarkNode* node,
                                    bool recurse,
                                    bool only_folders);
 
 // Add a JSON representation of |node| to the JSON |list|.
 void AddNode(const BookmarkNode* node, ListValue* list, bool recurse);
 
 void AddNodeFoldersOnly(const BookmarkNode* node,
                         ListValue* list,
                         bool recurse);
 
 bool RemoveNode(BookmarkModel* model,
                 int64 id,
                 bool recursive,
                 std::string* error);
 
 }  // namespace extension_bookmark_helpers
