Features

LimitedQueue

A Queue with a maximum number of items inside.

var queue = new LimitedQueue<Entity>(5); // Max of 5 items in the queue

queue.Enqueue(entity); // Enqueue an item

var result = queue.TryDequeue(); // Try to dequeue an item
if (result.Success)
{
    var item = result.Value; // Access dequeued item
}

queue.Enqueued += (sender, e) => {}; // Listen to enqueued items
queue.Dequeued += (sender, e) => {}; // Listen to dequeued items

LimitedStack

A Stack with a maximum number of items inside.

var stack = new LimitedStack<Entity>(5); // Max of 5 items in the stack

stack.Push(entity); // Push an item

var result = stack.TryPop(); // Try to pop an item
if (result.Success)
{
    var item = result.Value; // Access popped item
}

stack.Pushed += (sender, e) => {}; // Listen to pushed items
stack.Popped += (sender, e) => {}; // Listen to popped items

EntityList

A List to store unique items based on a key. A mix between a List<TEntity> and a Dictionary<TKey, TEntity>.

var list = new EntityList<int, Entity>(e => e.Id);

// Upsert a new item
// Add if the key does not exist in the list, update otherwise
list.Upsert(entity);

var entity = list.Find(1); // Find item by key

bool success = list.Remove(1); // Remove using the key

list.Added += (sender, e) => {}; // Listen to added entities
list.Updated += (sender, e) => {}; // Listen to updated entities
list.Removed += (sender, e) => {}; // Listen to removed entities
