Detailed Description

template<typename Int = int>
class cds::opt::v::random_permutation< Int >

Permutation generator of arbitrary length based on rand()

The class is suitable for opt::permutation_generator option.

The generator calculates n = rand() and produces the sequence [n % nLen, (n + 1) % nLen, ..., (n + nLen - 1) % nLen]. The generator does not allocate any memory.

Int template argument specifies the type of generated value, it should be any integer.
