| Description | |
|
A Stack is principally used in supoort of nesting - each level of nesting adds (pushes) a return value to the stack, retrieving (popping) the value on the way out.
Data is added to the top of the stack, and taken from the top, although methods are provided, such as GetEnumerator and Peek that allow processing over and above this simple first-in, first-out way.
The Stack may be constructed from scratch or from an existing stack or list. Control is provided over the capacity.
