Row Duplication
This article contains example code that shows the usage of the RowDuplication component.
Duplicating data
This example shows how RowDuplication can be used to duplicate incoming data.
public class MyRow
{
public string Value { get; set; }
}
public void Duplicate() {
var source = new MemorySource<MyRow>();
source.DataAsList.Add(new MyRow() { Value = "A" });
source.DataAsList.Add(new MyRow() { Value = "B" });
var duplication = new RowDuplication<MyRow>();
duplication.NumberOfDuplicates = 2;
var dest = new MemoryDestination<MyRow>();
source.LinkTo(duplication).LinkTo(dest);
Network.Execute(source);
foreach (var row in dest.Data)
Console.WriteLine($"Value:{row.Value}");
//Output
/* Value:A
Value:A
Value:A
Value:B
Value:B
Value:B
*/
}Duplicating with condition
This example shows how incoming data is only duplicated when a particular condition is met.
public class MyRow
{
public string Value { get; set; }
}
public void DuplicateWithPredicate() {
var source = new MemorySource<MyRow>();
source.DataAsList.Add(new MyRow() { Value = "A" });
source.DataAsList.Add(new MyRow() { Value = "B" });
var duplication = new RowDuplication<MyRow>();
duplication.NumberOfDuplicates = 2;
duplication.CanDuplicate =
row => row.Value == "A";
var dest = new MemoryDestination<MyRow>();
source.LinkTo(duplication).LinkTo(dest);
Network.Execute(source);
foreach (var row in dest.Data)
Console.WriteLine($"Value:{row.Value}");
//Output
/* Value:A
Value:A
Value:A
Value:B
*/
