Datastructure

A small .NET library of custom collection types.

`CircularHashSet<T>`

CircularHashSet<T> is a fixed-capacity set backed by a dictionary. When the set is full, adding a new key evicts the oldest entry in insertion order and inserts the new key.

Fixed capacity — size is set at construction and does not grow.
Insertion-order eviction — the oldest key is removed when capacity is exceeded.
Thread-safe — read/write operations use ReaderWriterLockSlim.
Duplicate keys — TryAdd returns false if the key is already present.

Install

dotnet add package AdvancedDataStructure

Example

using Datastructure;

var set = new CircularHashSet<string>(3);

set.TryAdd("a"); // true
set.TryAdd("b"); // true
set.TryAdd("c"); // true
set.TryAdd("d"); // true — "a" is evicted

set.Contains("a"); // false
set.Contains("d"); // true

set.GetKeys();              // current keys (order not guaranteed)
set.GetKeysByCreatedTime(); // keys ordered by insertion time

API

Member	Description
`CircularHashSet(int fixedSize)`	Creates a set with the given maximum capacity.
`bool TryAdd(T key)`	Adds a key, or evicts the oldest if full. Returns `false` if the key already exists.
`bool Contains(T key)`	Whether the key is in the set.
`T[] GetKeys()`	Snapshot of all keys.
`T[] GetKeysByCreatedTime()`	Keys ordered by insertion time.
`int Count`	Number of keys currently stored.
`void Clear()`	Removes all keys.
`void Dispose()`	Releases the lock.
