Constructor Detail

ReftableBatchRefUpdate

protected ReftableBatchRefUpdate(RefDatabase refdb,
                                 ReftableDatabase reftableDb,
                                 Lock lock,
                                 Repository repository)

Initialize.

Parameters:

refdb - The RefDatabase

reftableDb - The ReftableDatabase

lock - A lock protecting the refdatabase's state

repository - The repository on which this update will run

Method Detail

execute

public void execute(RevWalk rw,
                    ProgressMonitor pm,
                    List<String> options)

Execute this batch update.

The default implementation of this method performs a sequential reference update over each reference.

Implementations must respect the atomicity requirements of the underlying database as described in BatchRefUpdate.setAtomic(boolean) and RefDatabase.performsAtomicTransactions().

Overrides:

execute in class BatchRefUpdate

Parameters:

rw - a RevWalk to parse tags in case the storage system wants to store them pre-peeled, a common performance optimization.

pm - progress monitor to receive update status on.

options - a list of option strings; set null to execute without

applyUpdates

protected abstract void applyUpdates(List<Ref> newRefs,
                                     List<ReceiveCommand> pending)
                              throws IOException

Implements the storage-specific part of the update.

Parameters:

newRefs - the new refs to create

pending - the pending receive commands to be executed

Throws:

IOException - if any of the writes fail.

write

protected void write(ReftableWriter writer,
                     List<Ref> newRefs,
                     List<ReceiveCommand> pending)
              throws IOException

Writes the refs to the writer, and calls finish.

Parameters:

writer - the writer on which we should write.

newRefs - the ref data to write..

pending - the log data to write.

Throws:

IOException - in case of problems.
