Detailed Description

template<typename BidirIt>
class real::compat::detail::offset_cursor< BidirIt >

Maps offsets into a non-contiguous range's copy back to the caller's iterators by moving one iterator from the last offset mapped; std::next(first, offset) per mark would rewalk a std::list.

Template Parameters

BidirIt

The caller's iterator.

Constructor & Destructor Documentation

offset_cursor()

template<typename BidirIt >

real::compat::detail::offset_cursor< BidirIt >::offset_cursor ( BidirIt  it, std::size_t  offset  )

inline

Binds the cursor to it, which sits at offset of the sequence.

Parameters

[in]	it	An iterator into the caller's sequence.
[in]	offset	Its offset from the sequence start.

Member Function Documentation

to()

template<typename BidirIt >

BidirIt real::compat::detail::offset_cursor< BidirIt >::to ( std::size_t  offset )

inline

Moves to offset, either way.

Parameters

[in]

offset

An offset of the sequence, at most its length.

Returns

The caller's iterator at offset.
