Class AsyncKeyReaderWriterLock<TKey>

Namespace

SixLabors.ImageSharp.Web.Synchronization

Assembly

SixLabors.ImageSharp.Web.dll

Extension of the AsyncReaderWriterLock that enables fine-grained locking on a given key. Concurrent write lock requests using different keys can execute simultaneously, while requests to lock using the same key will be forced to wait. This object is thread-safe and internally uses a pooling mechanism to minimize allocation of new locks.

public class AsyncKeyReaderWriterLock<TKey> where TKey : notnull

Type Parameters

TKey

The type of the key.
