Examples

The following example demonstrates how to publish a message asynchronously on a topic.

First, initialize the cache.

ICache cache = CacheManager.GetCache("myCache");

Then, get messaging service from the cache.

IMessagingService messagingService=cache.MessagingService;

Then, get topic from the messagingService.

ITopic topic=messagingService.GetTopic("mytopic");  
if(topic==null)  //If topic not exists create it.
{
  topic=messagingService.CreateTopic("mytopic");
}

Then, publish message on the topic.

object payload = "mymessage"; 
Message message = new Message(payload);   //creating message
topic.PublishAsync(message, DeliveryOption.All).ContinueWith(task => 
{
    if (task.Status == TaskStatus.RanToCompletion)
    {
        Console.WriteLine("Message Published Successfully");
    }
    if (task.Status == TaskStatus.Faulted)
    {
        Console.WriteLine("Error has occurred");
    }
    if (task.Exception != null)
    {
        Console.WriteLine(task.Exception);
    }
});
