Collections
Collections are extensions to the C# collections that are useful for game programming.
Bag
A Bag is an un-ordered array of items with fast Add and Remove properties.
It is much faster than an array when removing items, and takes less space than a linked list.
Bag will resize itself only when it needs to.
var bag = new Bag<int>(3);
bag.Add(4);
bag.Add(8);
bag.Add(15);
// bag is now [4, 8, 15]
bag.Add(16); // array is extended here, capacity is now 4 instead of 3
bag.Remove(1);
// bag is now [4, 16, 15] with a capacity of 4
BitVector32
The BitVector32 class provides easy access to 32 individual bit flags.
Deque
Represents a collection of objects which elements can added to or removed either from the front or back; a double ended queue.
DictionaryExtensions
Extends all Dictionary<> classes with GetValueOrDefault(key, default).
KeyedCollection
A KeyedCollection is used like a Dictionary<>, except you provide a function that takes a value and return's it's key.
ListExtensions
Adds Shuffle(Random) to all IList<> classes.
Object Pooling
An ObjectPool<T> allows reuse of memory for a group of items to avoid Garbage Collection.
More information is in the Object Pooling documentation.
ObservableCollection
An ObservableCollection<T> manages an IList<T> of items firing ItemAdded, ItemRemoved, Clearing and Cleared events when the collection is changed.
