Interface TaskContext<S,OT>

Type Parameters:
S - The UDF type.
OT - The produced data type.
All Known Implementing Classes:
AbstractIterativeTask, BatchTask, IterationHeadTask, IterationIntermediateTask, IterationTailTask
public interface 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.
