Detailed Description

template<typename Block = unsigned long long, typename Allocator = std::allocator<Block>>
class sul::dynamic_bitset< Block, Allocator >::reference

Reference to a sul::dynamic_bitset bit.

As the bits in the sul::dynamic_bitset class are stored in an optimized way in blocks, it is not possible for the subscript operators to return a reference to a boolean. Hence this class is used as a proxy to enable subscript operator of the sul::dynamic_bitset class to be used as if it was an array of bools.
