They are template parameters in my code, I was just wondering what 
operator() and accumulate() do as I did not use them before.  Then the 
documentation just confused me as std::vector certainly does not have them.

Documenting the interface would certainly work, but referring to the 
current types should at least be a small improvement over the current 
state ;)
