Method Detail

getReceiver

public Receiver getReceiver(int minorFragmentId)

Description copied from interface: Exchange

Get the Receiver associated with the given minorFragmentId. Cannot be called until after setupSenders() and setupReceivers() have been called.

Parameters:

minorFragmentId - The minor fragment id, must be in the range [0, fragment.width).

Returns:

The materialized recevier for the given arguments.

getNewWithChild

protected PhysicalOperator getNewWithChild(PhysicalOperator child)

Specified by:

getNewWithChild in class AbstractSingle
