IStringMap.Keys

Syntax

Keys: ICollection;

Description

The Keys property returns the collection of map keys.

Example

Sub UserProc;
Var
    StrMap: IStringMap;
Begin
    StrMap := New StringMap.Create;
    StrMap.Add(GuidGenerator.Generate, "B");
    StrMap.Add(GuidGenerator.Generate, "A");
    StrMap.Add(GuidGenerator.Generate, "C");
    StrMap.Add(GuidGenerator.Generate, "E");
    Debug.WriteLine("Keys:");
    ShowValues(StrMap.Keys);
    Debug.WriteLine("Values:");
    ShowValues(StrMap.Values);
End Sub UserProc;

Sub ShowValues(myList: ICollection);
Var
    v: Variant;
Begin
    For Each v In myList Do
        Debug.Write(v + ' ');
    End For;
    Debug.WriteLine("");
End Sub ShowValues;

After executing the example a map of strings is generated. The generated GUID is used as a key. The map is sorted automatically by key values. Keys and element values are displayed in the development environment console.
