Cvdm.Timer

Schedules execution of a C# callback using a friendly System.Threading.Timer wrapper.

This library is easy to use with dependency injection:

• Inject ITimerFactory into your components, and use ITimerFactory.Create() to create an ITimer.
• In production use, register TimerFactory as an implementation of ITimerFactory.
• In your tests, mock ITimerFactory and set up ITimerFactory.Create() to return a mock ITimer. Raise the ITimer.Elapsed event manually as needed.
• Note: ITimer is disposable, and you should not inject it directly unless you know what you're doing. Use ITimerFactory instead.

Here's the API of the ITimer interface:

// Occurs when InitialDelay or Interval elapses
event Action Elapsed;

// Gets or sets the delay after which to first raise the Elapsed event. Non-positive values will
// make the event be immediately raised when the timer is started. If this is set on an active
// timer, call Start() to make the new value take effect.
TimeSpan Delay { get; set; }

// Gets or sets the interval at which to raise the Elapsed event. Non-positive values disables
// periodic elapsing. If this is set on an active timer, call Start() or Start(startTime) to
// make the new value take effect.
TimeSpan Interval { get; set; }

// Gets a value indicating whether the timer is active.
bool IsEnabled { get; }

// Starts raising the Elapsed event according to Interval and InitialDelay.
void Start();

// Uses startTime to set the InitialDelay property and immediately starts the timer.
void Start(DateTime startTime);

/// Stops raising the Elapsed event.
void Stop();

ITimer also implements IDisposable to dispose the wrapped System.Threading.Timer
