Constructor Detail

BatchRefUpdate

protected BatchRefUpdate(RefDatabase refdb)

Initialize a new batch update.

Parameters:

refdb - the reference database of the repository to be updated.

Method Detail

isAllowNonFastForwards

public boolean isAllowNonFastForwards()

Returns:

true if the batch update will permit a non-fast-forward update to an existing reference.

setAllowNonFastForwards

public BatchRefUpdate setAllowNonFastForwards(boolean allow)

Set if this update wants to permit a forced update.

Parameters:

allow - true if this update batch should ignore merge tests.

Returns:

this.

getRefLogIdent

public PersonIdent getRefLogIdent()

Returns:

identity of the user making the change in the reflog.

setRefLogIdent

public BatchRefUpdate setRefLogIdent(PersonIdent pi)

Set the identity of the user appearing in the reflog.

The timestamp portion of the identity is ignored. A new identity with the current timestamp will be created automatically when the update occurs and the log record is written.

Parameters:

pi - identity of the user. If null the identity will be automatically determined based on the repository configuration.

Returns:

this.

getRefLogMessage

public String getRefLogMessage()

Get the message to include in the reflog.

Returns:

message the caller wants to include in the reflog; null if the update should not be logged.

isRefLogIncludingResult

public boolean isRefLogIncludingResult()

Returns:

true if the ref log message should show the result.

setRefLogMessage

public BatchRefUpdate setRefLogMessage(String msg,
                                       boolean appendStatus)

Set the message to include in the reflog.

Parameters:

msg - the message to describe this change. It may be null if appendStatus is null in order not to append to the reflog

appendStatus - true if the status of the ref change (fast-forward or forced-update) should be appended to the user supplied message.

Returns:

this.

disableRefLog

public BatchRefUpdate disableRefLog()

Don't record this update in the ref's associated reflog.

Returns:

this.

isRefLogDisabled

public boolean isRefLogDisabled()

Returns:

true if log has been disabled by disableRefLog().

getCommands

public List<ReceiveCommand> getCommands()

Returns:

commands this update will process.

addCommand

public BatchRefUpdate addCommand(ReceiveCommand cmd)

Add a single command to this batch update.

Parameters:

cmd - the command to add, must not be null.

Returns:

this.

addCommand

public BatchRefUpdate addCommand(ReceiveCommand... cmd)

Add commands to this batch update.

Parameters:

cmd - the commands to add, must not be null.

Returns:

this.

addCommand

public BatchRefUpdate addCommand(Collection<ReceiveCommand> cmd)

Add commands to this batch update.

Parameters:

cmd - the commands to add, must not be null.

Returns:

this.

execute

public void execute(RevWalk walk,
                    ProgressMonitor update)
             throws IOException

Execute this batch update.

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

Parameters:

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

update - progress monitor to receive update status on.

Throws:

IOException - the database is unable to accept the update. Individual command status must be tested to determine if there is a partial failure, or a total failure.

newUpdate

protected RefUpdate newUpdate(ReceiveCommand cmd)
                       throws IOException

Create a new RefUpdate copying the batch settings.

Parameters:

cmd - specific command the update should be created to copy.

Returns:

a single reference update command.

Throws:

IOException - the reference database cannot make a new update object for the given reference.
