Examples of gri.tasks.AsyncTaskController

gri.tasks.AsyncTaskController
Object which is returned when an AsynchronousTask is executed. This allows us to check the status of the task and retrieve its outputs upon completion. We can optionally provide a means of killing the task prematurely. TODO: we will also want to add status listeners and especially a completion listener. this would also be the object that we would like to persist upon shutdown if possible. @author rogersda
