Tpl Dataflow on 7sharp9

Monster Zero - Revisited

7sharp9@mail.com (Dave Thomas) — Wed, 05 Jun 2013 00:00:00 +0000

This creature is capable of tremendous destruction due to it’s size, flight (with the creature’s wings also generating hurricane strength winds) and possesses several breath weapons (e.g., heat and energy).

What am I talking about here? Maybe it’s Monster Zero or King Ghidorah as it’s sometimes known. No it’s TPL Dataflow!

FSharp Dataflow agents III

This will be the last post on rebuilding the MailboxProcessor using TDF, here’s a quick discussion of the missing pieces…

First, lets start with the simple ones, these don’t really require much discussion.

DefaultTimeout
#

let mutable defaultTimeout = Timeout.Infinite

member x.DefaultTimeout
 with get() = defaultTimeout
 and set(value) = defaultTimeout <- value

This simply provides a mutable property using Timeout.Infinite as a default setting.

F# Dataflow Agents Part II

Right, no messing about this time, straight to the code.

Construction
#

This is pretty straight forward and I don’t want to detract from the important bits of this post, the only thing of note is the cancellationToken which is initialized to a default value using the defaultArg function if the optional parameter cancellationToken is not supplied. The TDF construct that we to use to perform most of the hard work is incomingMessages which is a BufferBlock<'Msg>.

F# Dataflow Agents Part I

This is going to be a new series on using TPL Dataflow with F#. First a little bit of history and background.

TPL Dataflows heritage and background
#

TPL Dataflow or (TDF) has been around for quite a while, it first surfaced more than a year ago as the successor to the Concurrency and Coordination Runtime (CCR) and with coming release of .Net 4.5 it will be part of the System.Threading.Tasks.Dataflow namespace. Elements of the now halted project Axum are also present within the design of TDF.
