AhoCorasickTrie

The AhoCorasickTrie class is an implementation of the Aho-Corasick algorithm for pattern matching in text.

Properties

• IgnoreCase: Determines if the trie ignores case during matching.

Methods

• void Add(string match): Adds a search phrase to the trie.
• IEnumerable<FindResult<TTag>> Find(string text): Finds all matches for the given text.

Example

var trie = new AhoCorasickTrie<string>();
trie.Add("apple", "fruit");
trie.Add("app", "prefix");
var results = trie.Find("apple pie");
foreach (var result in results)
{
    Console.WriteLine($"Match: {result.Tag}, Index: {result.Index}");
}

ConcurrentSet

The ConcurrentSet<T> provides a thread-safe set implementation.

Properties

• Count: The number of items in the set.
• IsEmpty: Indicates whether the set is empty.

Methods

• bool TryAdd(T item): Attempts to add an item.
• bool TryRemove(T item): Attempts to remove an item.
• void Clear(): Removes all items from the set.
• bool Contains(T item): Checks if the set contains an item.

Example

var set = new ConcurrentSet<int>();
set.TryAdd(1);
Console.WriteLine(set.Contains(1)); // True
set.TryRemove(1);

Deque

A double-ended queue supporting efficient operations at both ends.

Properties

• Count: The number of items in the deque.
• IsEmpty: Indicates whether the deque is empty.

Methods

• void AddFirst(T item): Adds an item to the front.
• void AddLast(T item): Adds an item to the end.
• T RemoveFirst(): Removes and returns the front item.
• T RemoveLast(): Removes and returns the last item.
• void Insert(int index, T item): Inserts an item at a specific index.
• void RemoveAt(int index): Removes an item at a specific index.
• T this[int index]: Gets or sets the item at the specified index.

Example

var deque = new Deque<int>();
deque.AddFirst(1);
deque.AddLast(2);

Console.WriteLine(deque.RemoveFirst()); // 1

DisjointSet

The DisjointSet class provides an implementation of the union-find algorithm, which is used to efficiently manage and query disjoint sets.

Properties

• Count: The number of disjoint sets.
• Size: The size of the underlying data structure.

Methods

• bool TryAdd(T item): Creates a new set containing the specified item.
• bool TryAdd(IEnumerable<T> items): Creates a new set containing the specified items.
• T Find(T item): Finds the representative of the set containing the specified item.
• void Union(T item1, T item2): Merges the sets containing the two specified items.
• bool AreConnected(T item1, T item2): Checks if two items belong to the same set.

Example

var set = new DisjointSet<int>();

// Add elements to the set
set.TryAdd(1);
set.TryAdd(2);
set.TryAdd(3);

// Union two elements
set.Union(1, 2);

// Find the representative of a group
Console.WriteLine(set.Find(1)); // Outputs: 1
Console.WriteLine(set.Find(2)); // Outputs: 1 (same group as 1)

// Check if two elements are in the same group
Console.WriteLine(AreConnected(1, 2)); // Outputs: False

DynamicDictionary

A dynamic dictionary that allows adding and retrieving dynamic properties.

Properties

• Source: The underlying dictionary.

Methods

• dynamic this[string name]: Gets or sets a value dynamically.
• bool TryGetMember(GetMemberBinder binder, out object result): Dynamically retrieves a member value.
• bool TrySetMember(SetMemberBinder binder, object value): Dynamically sets a member value.

Example

dynamic dict = new DynamicDictionary();
dict.Name = "Hyperbee";
Console.WriteLine(dict.Name); // Hyperbee

LinkedDictionary

A stack of dictionaries with layered key-value lookup that supports pushing and popping scopes.

Properties

• Name: The name of the current dictionary layer.
• Comparer: The equality comparer used for keys.

Methods

• void Push(IEnumerable<KeyValuePair<TKey, TValue>> collection): Pushes a new dictionary layer.
• void Push(string name, IEnumerable<KeyValuePair<TKey, TValue>> collection): Pushes a named dictionary layer.
• LinkedDictionaryNode<TKey, TValue> Pop(): Pops the top dictionary layer.
• bool TryGetValue(TKey key, out TValue value): Attempts to get a value by key.
• TValue this[TKey key, KeyValueOptions options]: Layered key-value assignment.

Example

var linked = new LinkedDictionary<string, string>();

// push an initial set of keys
linked.Push( new Dictionary<string, string>
{
    ["first"] = "default_first",
    ["last"] = "default_last",
    ["suffix"] = "",
} );

linked.Push( new Dictionary<string, string>
{
    ["first"] = "Tim",            // new scope masks original values
    ["last"] = "Jones",           // new scope masks original values
    ["address"] = "123 Main St."  // New key
} );

OrderedSet

A set that maintains the order of insertion.

Properties

• Comparer: The equality comparer used for items.
• Count: The number of items in the set.

Methods

• bool TryGetValue(T key, out T item): Gets a value if it exists.
• void Add(T item): Adds an item to the set.
• bool Remove(T item): Removes an item from the set.
• bool Contains(T item): Checks if the set contains an item.
• T this[T key]: Accesses the set by key.

Example

var orderedSet = new OrderedSet<int> { 1, 2, 3 };
Console.WriteLine(orderedSet[1]); // 1

PooledArray

A high-performance array pool for reusable arrays.

Important

The PooledArray class uses ArrayPool internally and must be disposed to avoid memory leaks. Always wrap instances in a using block or explicitly call Dispose().

Properties

• Count: The number of items in the array.
• T this[int index]: Gets or sets the item at the specified index.

Methods

• void Add(T item): Adds an item to the array.
• void Resize(int newSize): Resizes the array.
• void Remove(int index): Removes an item at the specified index.
• void Insert(int index, T item): Inserts an item at a specified index.
• void CopyTo(T[] destination, int sourceIndex, int destinationIndex, int count): Copies items to another array.

Example

using (var pooledArray = new PooledArray<int>(10))
{
    pooledArray.Add(42);
    Console.WriteLine(pooledArray[0]); // 42
}

PooledStack

A stack implementation built on PooledArray.

Important

The PooledStack class uses ArrayPool internally and must be disposed to avoid memory leaks. Always wrap instances in a using block or explicitly call Dispose().

Properties

• Count: The number of items in the stack.

Methods

• void Push(T item): Pushes an item onto the stack.
• T Pop(): Removes and returns the top item.
• T Peek(): Returns the top item without removing it.
• void Clear(): Removes all items from the stack.

Example

using (var stack = new PooledStack<int>())
{
    stack.Push(42);
    Console.WriteLine(stack.Pop()); // 42
}
