<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif"">Does anyone know if an insertion invalidates the end() iterator? The documentation in ADT/SparseMultiSet.h mentions that removal only invalidates the iterator of the object
being removed, but nothing on insertion. My understanding from reading the code seems to me that it doesn’t invalidate it, but I want to make sure as I’m not 100% sure here.<o:p></o:p></span></p>

<p class="MsoNormal"> The doubly linked list is implemented circular in Prev indices, and INVALID-terminated in Next indices.<o:p></o:p></p>

<p class="MsoNormal">Insertion will modify the Next index of the tail of the list for that key, and assigning it the index of the newly inserted entry.<o:p></o:p></p>

<p class="MsoNormal">Of course, if you had walked an iterator off the end of one of these lists (and thus, it's INVALID/equal to end()), that iterator will not be magically updated to point to the newly inserted value. This behavior is consistent with other
set-like data structures.<o:p></o:p></p>
