[Home]vector_c

Synopsis

template<
      typename T
    , T C1 = implementation-defined
    , T C2 = implementation-defined
    , ...
    , T CN = implementation-defined
    >
struct vector_c
{
};

Description

vector_c is a shorcut interface whose whole purpose is to make the creation of a vector of Integral Constants less verbose:

typedef vector_c<unsigned long,-1,0,1,1,-1,0,0,1,-1> data;

If vector_c didn't exist, instead of the above line you would have to write this:

typedef vector<
      integral_c<unsigned long,-1>
    , integral_c<unsigned long,0>
    , integral_c<unsigned long,1>
    , integral_c<unsigned long,1>
    , integral_c<unsigned long,-1>
    , integral_c<unsigned long,0>
    , integral_c<unsigned long,0>
    , integral_c<unsigned long,1>
    , integral_c<unsigned long,-1>
    > data;
