Wintellect's Power Collections for .NET

New Post: Can these collections be returned by WCF?

sun21170 — Fri, 03 Jul 2009 14:34:13 GMT

Can I have my WCF method return a power collection type? Will the power collection be serialized automatically? Or I need to write extra code to be able to return a power collection type from my WCF service method?

Thanks

Created Issue: Sign library with arbitrary key to be possible to deploy in GAC

This should be easy. Create arbitrary signing key and include in the library project. This is needed to be possible to deploy the library in the global assembly cache (GAC).

New Post: Redblack tree enumerator

geoffchappell — Sun, 17 May 2009 23:02:34 GMT

I've noticed significant memory growth when you enumerate the items in a large redblack tree (e.g. OrderedBag with millions of items). From what I can tell, it seems like the yield return pattern is pretty heavy weight when used with recursion. I imagine that the compiler created state objects are to blame for the growth. I ended up implementing a different enumerator that doesn't use the yield return and has no memory growth. Is this a known issue? any plans to address?

Commented Issue: Errors in unit test

kradewald — Wed, 13 May 2009 06:38:48 GMT

Test 'ToStringEnumerable' in ‘AlgorithmsTests’ class has errors. Errors are in lines 4331, 4333 and 4336. '.' (dot) is used in strings as a decimal separator(-8.9). I think that CultureInfo.CurrentCulture.NumberFormat.NumberDecimalSeparator should be used. Additionally in the Asserts, the first value should be the one that is expected, not the second one.
Comments: ** Comment from web user: kradewald **

The problem still exists: Without explicitly specifying a CultureInfo for ToString() and alike, numeric formatting may vary and thus the test fails.

AlgorithmsTests.ToStringEnumerable : Failed

NUnit.Framework.AssertionException: String lengths are both 22. Strings differ at index 19.
Expected: "{hello,8,{1,2,3},-8,9}"
But was: "{hello,8,{1,2,3},-8.9}"

New Post: Set of Sets

KevinBurton — Mon, 13 Apr 2009 19:15:01 GMT

I am having a bit of trouble understanding how I could efficiently implement a set of sets. I try the following:

Set<string> set1 = new Set<string>(new string[] { "A", "B", "C" });

Set<string> set2 = new Set<string>(new string[] { "C", "B", "A" });

Set<string> set3 = new Set<string>(new string[] { "B", "A", "C" });

Set<string> set4 = new Set<string>(new string[] { "A", "B", "D" });

Set<Set<string>> set5 = new Set<Set<string>>();

set5.Add(set1);

set5.Add(set2);

set5.Add(set3);

set5.Add(set4);

Assert.AreEqual(2, set5.Count, "set of sets should only contain two items");

Since sets 1 - 3 are the same I would expect set5 to only contain two items since the two adds after set2 and set3 are essentially adding the same set. Right? If this doesn't work I suspect that set4.Contains(setx) would not work also if setx is also a set of the same components as 1-3.

Ideas?

Thank you.

Kevin

Hi.

I sent it to you.

If someone else need's that library, just ask.

Commented Issue: Help File Still Not Fixed

devfuel — Thu, 29 Jan 2009 20:38:04 GMT

On 09/15/2008, I downloaded the latest help documentation file from the "Releases" page. The left pane shows all objects, members, etc., but the right pane always says "The address is not valid".
Comments: ** Comment from web user: devfuel **

As Morty mentions, this is happening because the file gets blocked. I had this error, too, then unblocked the file, and it works just fine.

Rated 5 Stars (out of 5) - I've been using this library for a good few years and it's totally top class. If for not other reason, you have to get it for the MultiDictionary!

New Post: BidirectionalDictionary

NewWorldMan — Thu, 18 Sep 2008 12:35:35 GMT

I've often needed such a data structure. However, it is almost always absent from data structure libraries! I've not seen an implementation of one for .NET either. C++ has such a data structure in the Boost libraries.

NewWorldMan — Thu, 18 Sep 2008 12:31:47 GMT

I'm not using C# 3.0 but I think it's still a useful library in that context. For starters there are the additional data structures. But I would guess that a number of the algorithms can be performed more conveniently using LINQ.

Plus lots of people will be stuck on .NET 2.0 for some time.

A similar but more powerful alternative is the C5 library.

C5 Generics Library

However, that has also not been updated to use C# 3. However, it has had more recent patches.

New Post: BidirectionalDictionary

ido_ran — Wed, 17 Sep 2008 19:25:35 GMT

It happen a lot to me that I need a bidirectional dictionary which is a dictioanry in which every key has value and each key is unique and each value is unique.$0This way it is possible to search for value by key and also search for key by value.$0$0$0$0$0It can be great addition to the libray.$0

This is probably related to a security feature in the html viewer. Right click the downloaded file > properties > unblock file. And it should work.

Project Description
Welcome to Power Collections, A Community Project to Develop the Best Public License type safe Collection Classes for .NET. Power Collections makes heavy use of .NET Generics. The goal of the project is to provide generic collection classes that are not available in the .NET framework. Some of the collections included are the Deque, MultiDictionary, Bag, OrderedBag, OrderedDictionary, Set, OrderedSet, and OrderedMultiDictionary.

This library was originally produced by Wintellect and is offered AS IS. It has been available on the Wintellect site for some time but we are placing it on Codeplex to encourage its growth and use.
Power Collections is free for all to use within the bounds of the standard Eclipse End user license agreement. If you feel you would like to contribute, please feel free to contact one of the project administrators.

skalkin — Tue, 19 Aug 2008 17:49:49 GMT

Too bad there were no updates since 2005, I think Power Collection would have benefited a lot from using C# 3.0.
Anyone knows a good alternative to it?

Commented Issue: Support Linq extension methods.

A very nice additon to PowerCollections would be the addition of Linq extension methods.
Comments: ** Comment from web user: DavidLarson **

Nevermind. I had a senior moment. For anyone that reads this just add "using System.Linq;" and you get linq extentions on the various .Net interfaces that are used by the PowerCollections.
