Re: [Boost-users] mpl::accumulate

9 Jun 2006

      Hello,

can someone tell me what exactly a parameter State in the mpl::accumulate means.

After the evaluation is finished, which type is returned by accumulate? State? Which types are
passed to the binary ForwardOp?

I do not exactly understand this example:

typedef vector types;

typedef accumulate<
      types
    , int_<0>
    , if_< is_float<_2>,next<_1>,_1 >
    >::type number_of_floats;

With Kind Regards,
