senf::safe_data_iterator Class Reference
Re-validating data iterator. More...#include <senf/Packets/SafeIterator.hh>
Detailed Description
Re-validating data iterator.This class is a wrapper around a PacketData::iterator instance. It will revalidate the iterator on every access. This keeps the iterator valid even when the data container is resized and thereby possibly relocated. The iterator will always point to the byte at the same offset from the packets beginning. If data is inserted before this iterators position, the data pointed to will of course change.
For this to work, the safe_data_iterator must be initialized with the container to which the iterator belongs. After this initialization it can be used like any other iterator.
