Interface Summary

Interface	Description
Driver<S extends Function,OT>	The interface to be implemented by all drivers that run alone (or as the primary driver) in a task.
ResettableDriver<S extends Function,OT>	This interface marks a Driver as resettable, meaning that will reset part of their internal state but otherwise reuse existing data structures.
TaskContext<S,OT>	The task context gives a driver (e.g., MapDriver, or JoinDriver) access to the runtime components and configuration that they can use to fulfil their task.

Class Summary

Class	Description
