bool | bm::is_interval (const BV &bv, typename BV::size_type left, typename BV::size_type right) BMNOEXCEPT |
Returns true if range is all 1s flanked with 0s Function performs the test on a closed range [left, right] true interval is all 1s AND test(left-1)==false AND test(right+1)==false Examples: 01110 [1,3] - true 11110 [0,3] - true 11110 [1,3] - false. More... | |
template<class BV > | |
bool | bm::find_interval_start (const BV &bv, typename BV::size_type from, typename BV::size_type &pos) BMNOEXCEPT |
Reverse find index of first 1 bit gap (01110) starting from position Reverse scan for the first 1 in a block of continious 1s. Method employs closed interval semantics: 0[pos..from]. More... | |

bool | bm::find_interval_end (const BV &bv, typename BV::size_type from, typename BV::size_type &pos) BMNOEXCEPT |
Reverse find index of first 1 bit gap (01110) starting from position Reverse scan for the first 1 in a block of continious 1s. Method employs closed interval semantics: 0[pos..from]. More... | |
