Abstract

Thorn SampleIO serves as an example for creating your own I/O thorns. Its code is clearly structured and well documented, and implements a very simple and light-weight but fully functioning Cactus I/O method.
Together with the documentation about I/O methods in the Cactus Users' Guide and the chapter about thorn IOUtil in the Cactus Thorn Guide you should be able to use this code and modify/extend it according to your needs.
