Hi, my name is Thomas Mullaly. I am currently an undergraduate in the Computer Science department at Kent State University and I am interested in contributing a generic linked-list library to Boost as a GSoC project and I just wanted to see if there is any interest from the Boost community about having these contributed as a library. I am implementing the linked lists project from 'Elements of Programming' (ch. 12, I think), and am trying to provide lists for both constant-time size and constant-time splice. My library currently implements a number of variations of both singly- and doubly-linked lists, and I have implemented a wrapper that adds a node count and acts as a counted list. While the basic list types are already implemented, there is still a lot of work to done on them. For my GSoC project I would like to integrate allocator support into them, clean up the existing interface, and create a generic interface to the different types of lists with the help of a mentor. By the end of my GSoC project I would like to have a functional list library to contribute to Boost. I feel that this would be a valuable library to Boost because the standards implementation limits you (depending on your library vendor) to either a constant time size() function with a linear time splice operations or constant time splice operations with a linear time size() function. With my implementations a developer will be able to pick and choose whether they want a singly or a doubly linked list, or if they want to use a counted listed instead of a non-counted list. Also their is variations in memory/runtime efficiency between the different variations of the list types which a developer will be able to choose for. Currently my list implementations make heavy use of the new features available in C++0x such as rvalue references and move semantics, but, I will be more than happy to create a backport of these for the current C++ standard so they can be included in Boost. If anyone is interested in the source code for my current list implementations I will be able to provide tarballs of them.
