Put(Value: Array);
Value is a data array that has to be exported.
The Put method exports data according to custom algorithm. The interface must be redefined in the custom class.
Class MyConsumer: Object, IDtRecordsetConsumer
Public Sub Put(Value: Array);
Var
TextFile: IFileInfo;
TextW: ITextWriter;
i, j: Integer;
Begin
TextFile := New FileInfo.Attach("c:\Out.txt");
If TextFile.Exists Then
TextW := TextFile.AppendText;
Else
TextFile.Open(FileOpenMode.Create, FileShare.Exclusive);
TextW := TextFile.AppendText;
End If;
For j := Value.GetLowerBound(2) To Value.GetUpperBound(2) Do
For i := Value.GetLowerBound(1) To Value.GetUpperBound(1) Do
If i = 0 Then
TextW.WriteString(Value[i, j] + " ");
Else
TextW.WriteLnDouble(Value[i, j]);
End If;
End For;
End For;
End Sub Put;
Public Sub Clear;
Var
TextFile: IFileInfo;
Begin
TextFile := New FileInfo.Attach("c:\Out.txt");
TextFile.Open(FileOpenMode.Create, FileShare.DenyWrite);
End Sub Clear;
End Class MyConsumer;
The example is a macro, containing implementation of the method, that exports data by custom algorithm. For algorithm work arrival as an array parameter, containing two data columns, is required. The first column contains symbolic data, the second- real numbers. During export data is output into the c:\Out.txt text file.
