public interface Task

extends MiningObject

The interface Task is an abstraction of the metadata needed to perform a mining operation. Tasks allow for subsequent reference to a task, reuse (re-execution), and deferred execution. Execution is initiated via Connection using the execute method, which in turn returns the execution handle used to further control the asynchronous execution of the task, or returns the status of the synchronous execution after completion.
