Method Detail

signalStop

public void signalStop()

Description copied from interface: Computation

A hook to inform that computation will be soon destroyed. It gives a way for long processing to cooperate to a quick shutdown.
This method is not invoked from the computation thread, it should only set some volatile flag and returns immediately.

processRecord

public void processRecord(ComputationContext context,
                          String inputStreamName,
                          Record record)

Description copied from interface: Computation

Process an incoming record on one of the computation's input streams.

Parameters:

context - The computation context object provided by the system.

inputStreamName - Name of the input stream that provides the record.

record - The record.

deserialize

public static Work deserialize(byte[] data)

serialize

public static byte[] serialize(Work work)
