+// StaticMapIterator provides increment and decrement operators to iterate
+// through a StaticMap map.  It does not provide *, -> operators, user should
+// use GetKeyPtr(), GetKey(), GetValuePtr() interfaces to retrieve data or
+// pointer to data.  StaticMapIterator is essentially a const_iterator.
