// This policy needs to work around a serious problem with this type of list: When we change
- // the size of any (direct or indirect) subelement of the list, This will change will render
- // the list completely invalid and unparseable since the 'byte' field will now be invalid.
+ // the size of any (direct or indirect) sub-element of the list, this will change will
+ // render the list completely invalid and un-parseable since the 'byte' field will now be
+ // invalid.
//
// The solution we apply is to store the *size* (i.e. the number of elements) of the list
- // when creating the container wrapper. We also maintain this value accross insert/erase
+ // when creating the container wrapper. We also maintain this value across insert/erase
// statements. Additionally we also safe the complete size of the data container (the vector
// holding the bytes). Since we only allow packet changes through this container while it
// exists, any change in the container size must be a change within this list and therefore
// just apply the size change directly to the bytes header (no need to traverse the
// list). However, the implementation of this approach would be much more complex and even
// more invasive and would probably suffer from the same restrictions to the user.
