Detailed Description

template<class Alloc>
class bm::bvector< Alloc >::counted_enumerator

Constant iterator designed to enumerate "ON" bits counted_enumerator keeps bitcount, ie number of ON bits starting from the position 0 in the bit string up to the currently enumerated bit.

When increment operator called current position is increased by 1.
