Styx is the foundation of a graph-based data flow framework for any kind of data processing. It is used heavily within Balder a data flow framework for property graph models on .NET/Mono. A process graph is composed of a set of process vertices connected to one another by a set of communication edges. Styx supports the splitting, merging, transformation and concurrent processing of data from input to output. It comes in three flavors:

The Pipes subproject is a lazy data flow framework.

var List = new List<Int32>() { 0, 1, 2, 2, 3, 4, 4, 5, 6, 2, 7, 8, 9, 1 }.
    DuplicateFilter().
    RangeFilter(2, 7).
    Skip(2).
    RandomFilter(0.25).
    ToList();

The Arrows subproject is an event-based data flow framework.

The Sensors subproject is an data source framework for all kinds of data emitting objects.

The following code will create an instance of a sensor producing a sinus wave. This could be used as a mockup for a voltage or current sensoring application - even when the frequency is very low here ;)
The WithTimestamp extension method will modify the output of the sensor to include the timestamp when the 'measurement' took place.
The ToActiveSensor extension method will transform the sensor from an lazy sensor to an event-sending sensor.
The SkipArrow extension method will skip the first event.
The ActionArrow extention method will call the given delegate for every received arrow/event.

new SinusSensor("/dev/sinus") {
    Frequency            = 0.05,
    Amplitude            = 240,
    MeasurementIntervall = TimeSpan.FromSeconds(1)
}.
WithTimestamp().
ToActiveSensor(Autostart: true).
SkipArrow(1).
ActionArrow(measurement => {
    Console.WriteLine(measurement.Timestamp + "\t" + measurement.Value);
});

You will see the current timestamp and value of a slow sinus wave on the console output.

The installation of Styx is very straightforward.
Just check out or download its sources and all its dependencies:

• Illias Commons for common .NET tools.
• NUnit for unit tests.
