Class KeyedMonitor<TKey>

Provides Monitor thread synchronization functionality over lock objects addressable by key(name). This class is thread-safe. The internal implementation is based on a fixed-size array of Dictionary objects to minimize inter-locking. Do not allocate/deallocate this class often, instead allocate once per service that needs to synchronize by keys and call methods on the instance.

Constructors

KeyedMonitor(IEqualityComparer<TKey>)

Declaration
public KeyedMonitor(IEqualityComparer<TKey> comparer = null)
Parameters
Type Name Description
System.Collections.Generic.IEqualityComparer<TKey> comparer

Methods

Enter(TKey)

Performs Monitor.Enter() on TKey value. Unlike TryEnter() this method does block

Declaration
public void Enter(TKey key)
Parameters
Type Name Description
TKey key

Exit(TKey)

Performs Monitor.Exit() on TKey value. Returns false in cases when lock was not taken which indicates an error in the calling control flow

Declaration
public bool Exit(TKey key)
Parameters
Type Name Description
TKey key
Returns
Type Description
System.Boolean

Synchronized(TKey, Action)

Executes an action under a lock() taken on TKey value

Declaration
public void Synchronized(TKey key, Action action)
Parameters
Type Name Description
TKey key
System.Action action

Synchronized<TResult>(TKey, Func<TResult>)

Executes a function under a lock() taken on TKey value

Declaration
public TResult Synchronized<TResult>(TKey key, Func<TResult> action)
Parameters
Type Name Description
TKey key
System.Func<TResult> action
Returns
Type Description
TResult
Type Parameters
Name Description
TResult

TryEnter(TKey)

Tries to perform Monitor.TryEnter() on TKey value. Returns true when lock was taken. Unlike Enter() this method does not block

Declaration
public bool TryEnter(TKey key)
Parameters
Type Name Description
TKey key
Returns
Type Description
System.Boolean
