BGL adjacency_list bundled properties io
by Naomi Fox 20 Mar '07

20 Mar '07

I am trying to use an adjacency list with bundled properties. So I type my graph data stucture as so: struct MyV { int numOnVertex; }; struct MyE { int numOnEdge; }; typedef adjacency_list<setS, setS, bidirectionalS, MyV, MyE> MyGraph; I would like to use the read function as defined in adjacency_list_io.hpp, so I can read in my special graph from a file that looks like below. # 3 vertices, v0.numOnVertex=6, v1.numOnVertex=5, v2.numOnVertex=3 v 0 6 1 5 2 3 # 3 edges, … [View More]

[mpl] Implementing includes_if
by Scott Meyers 20 Mar '07

20 Mar '07

I want to implement this: // returns whether Seq1 includes each of the elements in Seq2 // using Pred to determine type equality template<typename Seq1, // the putative superset typename Seq2, // the putative subset typename Pred> // whether T1 from Seq1 == T2 from Seq2 struct includes_if; My ultimate goal is to be able to determine whether every element in Seq2 is either in Seq1 or has a base class in Seq1. So the predicate I'll be passing in is a metafunction … [View More]

variant no compile time check on get<> type parameter
by Dizzy 20 Mar '07

20 Mar '07

Hello In order to minimize heap allocations but still allow for some OOP designs I needed a sort of union but one that it works for more than POD types. So I implemented such a thing myself to find out recently that boost::variant might do this already (boost does that often ;) ). However, initial testing for boost::variant shows that that there is no compile time check on the types allowed to instantiate boost::get on a variant, example: struct A {}; struct B {}; struct C{}; int main()… [View More]

Compiling boost for Windows Mobile
by Colin Irwin 20 Mar '07

20 Mar '07

Hi, I have some libraries of my own - of course using boost(!) - that I would like to use on the Windows Mobile platform. For those libraries that are non-header only, it's not clear to me how to change the platform to compile for. I'm using Microsoft Visual Studio .Net 2005 and so am hoping it should be possible. (Saying this, I fully understand that there may be libraries that don't work too well.) I've looked through the boost documentation and searched on the web/discussion groups, but … [View More]

Hi I would like to participate in Google Summer of Code in this year. I reviewed boost projects for last years and found an interesting project, I think. If you go to the link below you will see a short description for that library: http://www.crystalclearsoftware.com/cgi-bin/boost_wiki/wiki.pl?Google_Summe… The goal of this post is to define the main library features, which will be useful for users. Is that library useful for C++ community? If you are using(or have ever used) similar C++ … [View More]
