Detailed Description

template<typename Store, bool is_const>
class gf2::BitsIter< Store, is_const >

Two iterators over all the bits in a bit-store — one const and the other non-const.
The BitStore::bits() & BitStore::bits() const methods return the appropriate iterator type.

• BitsIter<Store, Word, false>: A non-const iterator over the bits in a bit-store (value type is BitRef).
• BitsIter<Store, Word, true>: A const iterator over the bits in a bit-store (value type is bool).

Both iterators allow us to view the bit values but only the non-const iterator allows us to set the bit values.

The two iterator types have lots of common functionality. To avoid code duplication we add a final boolean template parameter is_const to distinguish the two types. Depending on the value of is_const, the std::conditional_t is used to choose the correct type for the store pointer and value type.

Example

BitVec v{10};
assert_eq(v.to_string(), "0000000000");
for (auto&& bit : v.bits()) bit = true;
assert_eq(v.to_string(), "1111111111");
