IMatrixIterator.ItemID

Syntax

ItemID: Integer;

Description

The ItemID property returns index of the element, on which the iterator cursor is currently put.

Example

Sub Main;

Var

M: Matrix[1];

Mm: IMatrix;

Iter: IMatrixIterator;

i: Integer;

Begin

For i := 0 To 10 Do

M[i] := i * 2;

End For;

Mm := M As IMatrix;

Iter := Mm.CreateIterator;

Iter.Move(IteratorDirection.First);

While Iter.Valid Do

If (Iter.ItemID Mod 2) = 0 Then

Debug.WriteLine("Value " + Iter.ItemID.ToString + ": " + Iter.Value);

End If;

Iter.Move(IteratorDirection.Next);

End While;

End Sub Main;

After executing the example a matrix is created and populated with values. This matrix is used to get an iterator, and elements values with even index in a matrix are output in a cycle.
