IQueue.Dequeue

Syntax

Dequeue: Variant;

Description

The Dequeue method gets a value of the element that is placed as the first one from a queue.

Comments

After extracting, the element is removed from a queue.

Example

Sub UserProc;
Var
    Que: IQueue;
    i: Integer;
Begin
    Que := New Queue.Create;
    For i := 0 To Math.RandBetweenI(50, 100) Do
        Que.Enqueue("Value " + Math.RandBetweenI(0, 100).ToString);
    End For;
    For i := 0 To Math.RandBetweenI(0, 50) Do
        Que.Dequeue;
    End For;
    i := Que.Count;
End Sub UserProc;

After executing the example a queue of random elements is created, part of elements is extracted, and the "i" variable contains the number of elements left in the queue.
