Interface PactTaskContext<S,OT>

Type Parameters:

S - The UDF type.

OT - The produced data type.

All Known Implementing Classes:

AbstractIterativePactTask, IterationHeadPactTask, IterationIntermediatePactTask, IterationTailPactTask, RegularPactTask

public interface PactTaskContext<S,OT>

A runtime task is the task that is executed by the flink engine inside a task vertex. It typically has a PactDriver, and optionally multiple chained drivers. In addition, it deals with the runtime setup and teardown and the control-flow logic. The later appears especially in the case of iterations.
