Method Detail

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.

isAbortedCommand

protected boolean isAbortedCommand(String commandId)

getCommand

protected BulkCommand getCommand(String commandId)

getCurrentCommand

public BulkCommand getCurrentCommand()

processBatchOfDocuments

protected void processBatchOfDocuments(List<String> batch)

loginSystemOrUser

protected NuxeoLoginContext loginSystemOrUser(String username)
                                       throws LoginException

Throws:

LoginException

startBucket

public void startBucket(String bucketKey)

Can be overridden to init stuff before processing the bucket

endBucket

public void endBucket(ComputationContext context,
                      BulkStatus delta)

Can be overridden to write to downstream computation or add results to status

processFailure

public void processFailure(ComputationContext context,
                           Throwable failure)

Description copied from interface: Computation

Called when Computation.processRecord(org.nuxeo.lib.stream.computation.ComputationContext, java.lang.String, org.nuxeo.lib.stream.computation.Record) or Computation.processTimer(org.nuxeo.lib.stream.computation.ComputationContext, java.lang.String, long) fails and cannot be retried.

Specified by:

processFailure in interface Computation

Overrides:

processFailure in class AbstractComputation

updateStatus

public static void updateStatus(ComputationContext context,
                                BulkStatus delta)

compute

protected abstract void compute(CoreSession session,
                                List<String> ids,
                                Map<String,Serializable> properties)
