public interface TransactionLog

Interface used to notify a logging subsystem of transaction events.

Method Summary

void	begin(Xid xid)
void	commit(Xid xid, Object logMark)
int	getAverageBytesPerForce()
int	getAverageForceTime()
String	getXMLStats()
Object	prepare(Xid xid, List branches) log prepare for the global xid xid and the list of TransactionBranchInfo branches
Collection	recover(XidFactory xidFactory) Recovers the log, returning a map of (top level) xid to List of TransactionBranchInfo for the branches.
void	rollback(Xid xid, Object logMark)

Method Detail

begin

void begin(Xid xid)
           throws LogException

Throws:

LogException

prepare

Object prepare(Xid xid,
               List branches)
               throws LogException

log prepare for the global xid xid and the list of TransactionBranchInfo branches

Parameters:

xid - global xid for the transactions

branches - List of TransactionBranchInfo

Throws:

LogException

commit

void commit(Xid xid,
            Object logMark)
            throws LogException

Throws:

LogException

rollback

void rollback(Xid xid,
              Object logMark)
              throws LogException

Throws:

LogException

recover

Collection recover(XidFactory xidFactory)
                   throws LogException

Recovers the log, returning a map of (top level) xid to List of TransactionBranchInfo for the branches. Uses the XidFactory to reconstruct the xids.

Parameters:

xidFactory -

Returns:

Map of recovered xid to List of TransactionBranchInfo representing the branches.

Throws:

LogException

getXMLStats

String getXMLStats()

getAverageForceTime

int getAverageForceTime()

getAverageBytesPerForce

int getAverageBytesPerForce()
