An IceStorm publisher is an Ice client application that sends requests to a Topic hosted by the IceStorm service.

The IceStorm/weather demo program provides a complete publisher application. It’s available in all programming languages.

The implementation of the weather sensor (or collector) can be summarized as follows:

  1. Create a proxy for the IceStorm TopicManager . This is the primary IceStorm object, used by both publishers and subscribers.
  2. Obtain a proxy for the weather topic from the TopicManager, either by creating the topic if it does not exist, or by retrieving the proxy for the existing topic.
  3. Obtain a proxy for the weather topic's "publisher object" by calling getPublisher on the topic proxy. This proxy is provided for the purpose of publishing messages, and therefore is narrowed to the topic interface (WeatherStation).
  4. Collect and report readings by invoking on the proxy created in the previous step.
