Detailed Description

template<typename T, int shift_count = 1, bool terminal_calc = ( shift_count >= ( std::numeric_limits<T>::digits ) )>
struct at::gray_tools::gray_to_bin_helper< T, shift_count, terminal_calc >

gray_to_bin_helper contains a static helper method to generate binary code from gray code. This is a recursive template that will terminate when the specialization below is used.

Member Function Documentation

template<typename T, int shift_count = 1, bool terminal_calc = ( shift_count >= ( std::numeric_limits<T>::digits ) )> void at::gray_tools::gray_to_bin_helper< T, shift_count, terminal_calc >::calculate (  T &    io_value )  [inline, static]

calculate will calculate the inverse of the gray code conversion above. The value is passed by reference and is modified in place. In general the computation is : value ^= value >> 1; value ^= value >> 2; value ^= value >> 4; // terminate here for 8 bit value ^= value >> 8; // terminate here for 16 bit value ^= value >> 16; // terminate here for 32 bit value ^= value >> 32; // terminate here for 64 bit Parameters: the  value being computed
