Event Manager Code - EventPublisherAttribute.cs

The EventPublisherAttribute is a C# attribute that decorates a function that publishes an internal event. Any function that publishes an event out to our little event broker should decorate itself with this attribute.For example:

[EventPublisher("Brokerage.TradingSystem.Trade.ReceivedFromBackend")]
public void OnTradeReceived(Trade trade)
{
  .......
  EventManager.Fire(this, "Brokerage.TradingSystem.Trade.ReceivedFromBackend", 
                    tradeArgs);
}

Here is the code:

 {
  private string _topicName;
  
  public EventPublisherAttribute()
  {
  }

  /// 

  /// EventPublisherAttribute

  /// The name of the event
  public EventPublisherAttribute(string topicName)
  {
   this._topicName = topicName;
  }
  
  public string Topic
  {
   get
   {
    return this._topicName;
   }
   set
   {
    this._topicName = value;
   }
  }
 }
}
