[Boost-users] [accumulators] Help required for using UDT as Sample

25 Feb 2009

      Hi,
 I am using boost::accumulator for finding min (among other things). It works fine when I use a POD as Sample.

ex:
accumulator_set< double, features tag::min > acc;
acc(1.0);
acc(5.0);
....

I have my own data type, time stamp and value. I would like to get the min Sample with corresponding time stamp.

class time_val {
public:
  time_t _time;
  double _value;

/* I have overloaded operators: <, >, ==, != */
/* Have provided copy constructor */
};

When I try:
accumulator_set< time_val, features tag::min > acc;

I get a whole lot of compilation errors. Is there any way I can make a UDT as a sample?

regards,
-dhruva
