Tpl Dataflow walkthrough - Part 5

Tpl Dataflow walkthrough - Part 5 this post is a complete walkthrough of a web crawler sample that was build purely by using Tpl Dataflow . it was built on .NET 4.5 / C# 5 (on a virtual machine using VS 11 ). I will analyze each part of this sample, both by discussing the Dataflow blocks and the patterns in used. the sample code is available in here (it is a VS 11 project). during the walkthrough you will see the following Tpl Dataflow blocks: TransformBlock TransformManyBlock ActionBlock BroadcastBlock...

Tpl Dataflow (IDataflowBlock) - Part 5

Tpl Dataflow ( IDataflowBlock ) - Part 5 the previous post discus the concept ITargetBlock and ISourceBlock , which is the TDF consumer/Producer contract. you can find all the post in this series under the TDF tag. this post focus on the IDataflowBlock contract which is the life-time management contract for all data-flow's blocks. the IDataflowBlock define single property and 2 methods: Code Snippet public interface IDataflowBlock { Task Completion { get ; } void Complete(); void Fault( Exception...

Tpl Dataflow (ISourceBlock) - Part 3

Tpl Dataflow (ISourceBlock) - Part 3 the previous post discus the concept ITargetBlock which is the TDF consumer contract. this post will focus on the source block which is the producer contract. as mention in previous post, sources and targets engage in a protocol for transferring messages between them. Source Block: the source block main responsibility is to produce (or manipulate) data which will be consume by the target . as we learn in previous post the target may consume the data either directly...
