Instance Method Details

#run(endpoint) ⇒ Object

Runs this task. Gets passed an endpoint that can be used to communicate values back to the master. Every time you write a value to that endpoint (using #send), the server will call #incoming_message on the task object in the master process. This allows return values and other communication from children to the master (and to the caller in this case).
