Clone  
Method  
Make a new Queue that is a clone of the current Queue
Queue Class
System.Collections NameSpace
CF1.  Function Clone : Object;
CF : Methods with this mark are Compact Framework Compatible
Description
A new Queue is created with the same number of elements, and entries as the current Queue.
 
When the current queue holds reference (non primitive) data types, the cloned queue element values still refer to the same objects that current queue elements refer to. This is what is referred to as a shallow copy. A deep copy would create new versions of the referred objects.
Notes
You are obliged to cast the resultant Object to a Queue before assignment to a Queue variable.

{$APPTYPE CONSOLE}

uses
  System.Collections;

var
  Source, Target : System.Collections.Queue;
  Enumerator     : IEnumerator;

begin
  // Create our queues
  Source := Queue.Create;
  Target := Queue.Create;

  // Add entries to the source queue
  Source.EnQueue('First');
  Source.EnQueue('Second');
  Source.Enqueue('Third');

  // Display the queue
  Console.WriteLine('Source queue :');
  Console.WriteLine;
  Enumerator := Source.GetEnumerator;
  while Enumerator.MoveNext do
    Console.WriteLine(Enumerator.Current.ToString);

  // Clone the queue!
  Target := Queue(Source.Clone);

  // Display the target
  Console.WriteLine;
  Console.WriteLine('Cloned queue :');
  Console.WriteLine;
  Enumerator := Target.GetEnumerator;
  while Enumerator.MoveNext do
    Console.WriteLine(Enumerator.Current.ToString);

  Console.Readline;
end.
