Method Detail

init

public void init(ComputationContext context)

Description copied from interface: Computation

Called when the framework has registered the computation successfully. Gives users a first opportunity to schedule timer callbacks and produce records.

Specified by:

init in interface Computation

Overrides:

init in class AbstractTransientBlobComputation

Parameters:

context - The computation context object provided by the system.

processTimer

public void processTimer(ComputationContext context,
                         String key,
                         long timestamp)

Description copied from interface: Computation

Process a timer callback previously set via ComputationContext.setTimer(String, long).

Specified by:

processTimer in interface Computation

Overrides:

processTimer in class AbstractComputation

Parameters:

context - The computation context object provided by the system.

key - The name of the timer.

timestamp - The timestamp (in ms) for which the callback was scheduled.

processRecord

public void processRecord(ComputationContext context,
                          String documentIdsStreamName,
                          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.

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

record - The record.

protected Long getTotal(String commandId)

appendToFile

protected Path appendToFile(String commandId,
                            byte[] content)

                                        String commandId,
                                        byte[] header,
                                        byte[] footer)

saveInTransientStore

                                      String storeName)

getOutputStream

protected String getOutputStream(String commandId)

finishBlob

protected void finishBlob(ComputationContext context,
                          String commandId)
