Acknowledgements

The Signal Network library aims to facilitate the implementation and interconnection of objects into signal networks using Boost.Signals. To see the rationale behind the Signal Network library, please visit the associated GSoC page.

[Warning]

Warning

Signal Network is not a part of the Boost libraries. It is being developed as a part of Google Summer of Code program.

If you would like some more information about why one would want to connect objects into a signal-based network, read my exploration of Dataflow-oriented programming approaches in C++.
If you'd like to try out the library
- keep in mind that the interface is highly unstable at this point
- see the Quick Start section.
If you are interested in the progress of the implementation, see
- News section of the Signal Network GSoC page
- Discussion on Boost Community Feedback
