Project Description

NPipeline is a .NET port of the Apache Commons Pipeline components. It is a lightweight set of utilities that make it simple to implement parallelized data processing systems.

Data objects flowing through the pipeline are processed by a series of independent user-defined components called Stages . A pipeline may have a number of different branches of execution, each of which is a fully qualified Pipeline in its own right.
