Does an element within a linked list/map keep its address forever?

Hello,
when I get the address of an element within a linked list or map, does the address to this element always stay the same (as long as I don't use MergeList(), CopyList(), etc.)?

Yes linked-list elements will remain at the same address. It should be safe even after MergeList() also. Only links are changed when rearranging list elements not the addresses of the elements. That's why they are called 'linked' lists.
Map elements may change.
@Edit: My first response ignored Map elements.

Yeah, that's what I suspected, thanks.

map elements may change if it resizes.
