PxtlCa.Collections

This is an old collections library made by Martin Zarate (AKA Pxtl) in 2008.

Provides customizable Dictionaries and Lists.

VirtualList, VirtualDictionary

These are simple implementations of IList<T> and IDictionary<TKey, TValue> that provide a wrapper around an existing IList or IDictionary (defaulting to the System.Collections.Generics implementations) and implement every operation with a virtual modifier so that they can be conveniently subclassed and overridden. This makes it convenient to implement custom collections.

FilteredDictionary

FilteredDictionary is IDictionary<TKey, TValue> that allows one or more "filters", or "mixins". Each one changes the dictionary's functionality, for example by firing events or by providing default value logic for the dictionary so that it will never throw a KeyNotFoundException. Available filters are provided in PxtlCa.Collections.DictionaryFilters. For convenience, pre-built FilteredDictionaries exist in the form of AutoConstructingDictionary, DefaultingDictionary, and ChangeNotingDictionary, which each of which are a subclass of FilteredDictionary with a Filter baked-in.

PxtlCa.ObjectProxies

A second project PxtlCa.ObjectProxies is included in the source but not built for the nuget package. It is a set of pseudo-pointer generics in C#. I don't really remember what I was going for with these. This may be mostly an artifact of .NET 2.0 since Expression objects have replaced the need for that generally.

AI Disclosure

While this code is primarily hand-made, a Qwen 3.5 AI was used to modernize the codebase a bit and add the test classes.
