Description

Add a Mathematical Set class to Boo to support set operations.

  • A set can be created from any IEnumerable
  • Methods include: intersection, union, (left/right)difference and IsSubSet
  • Operators: a | b (union), a & b (intersection), a - b (leftdifference), a ^ b (difference), a < b (strict subset), a <= b (subset).

Attached is a C# file that implements this proposed Set class.

The Iesi.Collections library (http://www.codeproject.com/csharp/sets.asp) could also be of interest here. The library contains a number of set classes with different features. The library is distributed with NHibernate, where the Iesi.Collections.ISet interface is used for set mappings.

I don't see the need to distribute a set library with Boo, unless set operations should become part of the language (I guess that won't happen). The standard .NET class library could need a set class, though.

Most excellent. Thanks! This will probably be introduced to Boo.Utilities when Rodrigo gets around to creating the basic framework, COUGH COUGH

Attached slightly adjusted Set class:

  • comments
  • removed one of the constructors that was causing a bug

Added NUnit Test script for Set class

Most important thing I forgot to say:
