KeyedSignalTKey, TResult Class

Represents a wait-by-key async signaling operation that can work with multiple concurrent waiters per key. Multiple callers await a task associated with a key; another single thread then signals completion with a result or failure with an exception for that key.

Inheritance: Object KeyedSignalTKey, TResult

Implements: IAsyncDisposable, IDisposable

Type Parameters

TKey: Key type, e.g., a Guid.
TResult: Result type delivered to all waiters when signaled.

Remarks

Pruning happens periodically to avoid orphaned waiters when all callers timeout from no signal.

Constructors

KeyedSignalTKey, TResult

Creates a new instance of the KeyedSignalTKey, TResult class.

Properties

PendingKeysCount

Gets the number of pending keys that have waiters.

Methods

Dispose	Releases all the resources used by the KeyedSignalTKey, TResult object.
DisposeAsync	Performs application-defined tasks associated with freeing, releasing, or resetting unmanaged resources asynchronously.
Equals	Determines whether the specified object is equal to the current object. (Inherited from Object)
Fail	Fails all current waiters for key with ex. New waiters added after this call for same key will await a subsequent signal/fail.
GetHashCode	Serves as the default hash function. (Inherited from Object)
GetType	Gets the Type of the current instance. (Inherited from Object)
Signal	Signals all current waiters for key with result. New waiters added after this call for same key will await a subsequent signal/fail.
ToString	Returns a string that represents the current object. (Inherited from Object)
TryFail	Tries to fail all current waiters for key with ex. New waiters added after this call for same key will await a subsequent signal/fail.
TrySignal	Tries to signal all current waiters for key with result. New waiters added after this call for same key will await a subsequent signal/fail.
Wait	Waits synchronously for the specified key to be signaled or failed. Multiple concurrent waiters on the same key complete together.
WaitAsync	Asynchronously waits for key to be signaled (or failed). Multiple concurrent waiters on the same key complete together.
