Detailed Description

Implements conversion from a chunk to asio::const_buffer.

Iterators for an InputBuffer will iterate over the avro of chunks, so internally they contain an iterator. But the iterator needs to be convertable to an asio buffer for use in boost::asio functions. This class wraps the iterator with a cast operator to do this conversion.

Member Data Documentation

BufferImpl::ChunkList::const_iterator avro::detail::InputIteratorHelper::iter_

Conversion operator.

It doesn't check for null, because the only the only time the chunk should be null is when it's the iterator end(), which should never be dereferenced anyway. the current iterator

Referenced by data(), and size().
