    Class AsyncReentrantMutex

    Extends AsyncMutex to support reentrancy.

    Inheritance
    object
    AsyncReentrantMutex
    Namespace: Neon.Tasks
    Assembly: Neon.Common.dll
    Syntax
    public class AsyncReentrantMutex
    Remarks

    Unlike the AsyncMutex class, this class supports reentrency, meaning that once an asynchronous Task flow has acquired the mutex, any additional acquistions by nested operations will also be accepted.

    var mutex = new AsyncReentrantMutex();
    

    await mutex.ExecuteActionAsync( async () => { // Protected code

        await mutex.ExecuteActionAsync(   // <--- This doesn't block
            async () =>
            {
                // More protected code
            });
    });</code></pre>
    

    The ExecuteFuncAsync<TResult>(Func<Task<TResult>>) can be used to execute an async function that returns a result instead.

    AsyncReentrantMutex is disposable. Calling dispose will cause ObjectDisposedException to be thrown on any tasks waiting to acquire the mutex.

    Constructors

    AsyncReentrantMutex()

    Constructor.

    Declaration
    public AsyncReentrantMutex()

    Methods

    Dispose()

    Releases any important resources associated with the instance.

    Declaration
    public void Dispose()
    Remarks
    note

    This method will cause a ObjectDisposedException to be thrown on any task waiting to acquire this mutex.

    Dispose(bool)

    Releases any important resources associated with the instance.

    Declaration
    protected void Dispose(bool disposing)
    Parameters
    Type Name Description
    bool disposing

    Pass true if the instance is being disposed as opposed to being finalized.

    ExecuteActionAsync(Func<Task>)

    Acquires the mutex and then invokes the asynchronous action passed. This method returns after the action completes.

    Declaration
    public Task ExecuteActionAsync(Func<Task> action)
    Parameters
    Type Name Description
    Func<Task> action

    The asynchronous action.

    Returns
    Type Description
    Task

    The tracking Task.

    ExecuteFuncAsync<TResult>(Func<Task<TResult>>)

    Acquires the mutex and then invokes the asynchronous function passed, returning the function's result.

    Declaration
    public Task<TResult> ExecuteFuncAsync<TResult>(Func<Task<TResult>> function)
    Parameters
    Type Name Description
    Func<Task<TResult>> function

    The asynchronous function.

    Returns
    Type Description
    Task<TResult>

    The function result.

    Type Parameters
    Name Description
    TResult

    Specifies the result returned by the async function.

    ~AsyncReentrantMutex()

    Finalizer.

    Declaration
    protected ~AsyncReentrantMutex()
