inline Iterator(const typename vec_t::iterator &in_it)

Iterator(const Iterator&) = default

Iterator &operator=(const Iterator&) = default

inline Iterator &operator++()

inline Iterator &operator--()

inline bool operator==(const Iterator &in) const

Iterator comparisons.

inline bool operator!=(const Iterator &in) const

inline bool operator<(const Iterator &in) const

inline bool operator<=(const Iterator &in) const

inline bool operator>(const Iterator &in) const

inline bool operator>=(const Iterator &in) const

inline T &operator*()

Return a reference to the element pointed to by this iterator; may advance iterator.

inline const T &operator*() const

Return a const reference to the element pointed to by this iterator.

inline operator bool() const

Is this iterator pointing to a valid position in the vector?

inline Iterator begin()

Return an iterator pointing to the first position in the vector.

inline const Iterator begin() const

Return a const iterator pointing to the first position in the vector.

inline Iterator end()

Return an iterator pointing to just past the end of the vector.

inline const Iterator end() const

Return a const iterator pointing to just past the end of the vector.

Private Members

vec_t::iterator it

Todo:

Add a const iterator, and probably a reverse iterator.
