Intertwine: Normalizing Interface Invocations

This post has been superseded by a new post in 2022
See michael.gr - Intertwine

This is a C# project that I did back in 2011. It consists of a (rather informal) white paper which describes the project, and a zip file containing the source code in the form of a Microsoft Visual Studio solution.

Here is the abstract:

A mechanism is proposed for converting (entwining) method call invocations of any interface to a general purpose single-method normal form, and converting back (untwining) from the normal form to interface invocations, so that operations can be performed on the normal form in a way agnostic to the interface being invoked. The normal form is a delegate in C# or a functional interface in Java, realized as object AnyCall( int selector, object[] parameters ). A DotNet implementation is provided in C#, though the discussion also applies to Java.

• A hand-crafted solution (page 3)
• Automating with Intertwine (page 6)

• Appendix 3: Things to fix (page 8)
