Collections

A handful of data structures and LINQ-like extensions that the BCL doesn't give you out of the box. Everything here is either (a) a collection with a specific behaviour you'd otherwise reinvent, or (b) a tiny extension that saves you a one-liner you write on every project.

Pages in this section

• Circular Queue — fixed-capacity FIFO that drops the oldest item when full. Ring buffer without the fuss.
• Handler Registry — predicate/action pairs with first-match or all-match dispatch and a stash/pop mechanism for testing.
• Type Registry — Type-keyed dictionary with GetOrAdd semantics; the backbone of pluggable systems.
• Lazy Value Cache — memory-cached lazy initialisation with per-entry expiration.
• Extensions — EnumerableExtensions, CollectionExtensions, AsyncEnumerableExtensions and the InsertAt helpers.
