Sort
This article contains example code that shows the usage of the Sort component.
Basic usage
The sort is a simply transformation that sort your input data by a given comparison func. Please note that the sort is a blocking transformation - it will wait for all input data to arrive, before it starts sorting your data.
Instead of using the Sort in your data flow, you could also create a SortedSet as storage collection for you incoming data in a MemoryDestination. This will also allow you to sort you data, as shown in this example coding.
public class MyRow
{
public int Number { get; set; }
public string Value { get; set; }
}
var source = new MemorySource<MyRow>();
source.DataAsList.Add(new MyRow() { Number = 2, Value = "A" });
source.DataAsList.Add(new MyRow() { Number = 5, Value = "B" });
source.DataAsList.Add(new MyRow() { Number = 1, Value = "Y" });
source.DataAsList.Add(new MyRow() { Number = 3, Value = "C" });
source.DataAsList.Add(new MyRow() { Number = 3, Value = "X" });
source.DataAsList.Add(new MyRow() { Number = 1, Value = "D" });
source.DataAsList.Add(new MyRow() { Number = 4, Value = "E" });
var dest = new MemoryDestination<MyRow>();
Comparison<MyRow> comp = new Comparison<MyRow>(
(x, y) => {
if (y.Number > x.Number) return 1;
else if (y.Number < x.Number) return -1;
else return 0;
});
Sort<MyRow> sort = new Sort<MyRow>(comp);
source.LinkTo(sort);
sort.LinkTo(dest);
Network.Execute(source);
//Output:
//Number 5 - Value B
//Number 4 - Value E
//Number 3 - Value C
//Number 3 - Value X
//Number 2 - Value A
//Number 1 - Value Y
//Number 1 - Value D
foreach (var row in dest.Data)
Console.WriteLine("Number " + row.Number + " - Value " + row.Value);
