Interface DeferredCompositionContext

    • Method Detail

      • getPartitionInfo

        PartitionInstanceInfo getPartitionInfo()
        Returns partition id information for the partition being composed. Most operators should not need to call this method since their output will tend to be a function of the input. This is commonly used for I/O operators which, for example, must chose the output file name based on the partition ID.
        Returns:
        partition id information for the partition being composed.
      • getNodeAllocation

        NodeAllocationPlan getNodeAllocation()
        Returns the node allocation for the graph to which this operator belongs.
        Returns:
        the node allocation
      • getDistributedCallableContext

        DistributedCallableContext getDistributedCallableContext()
        Public only as a matter if implementation; operator authors should not invoke this method.

        Returns the distributed callable context in which we are being composed.

        Returns:
        the distributed context
      • getStatisticsRegistry
