Constructor Detail

LoggerPerTransactionStrategy

public LoggerPerTransactionStrategy(IDataLoggerFactory loggerFactory)

per thread a new Logger cpould be instanciated with aid of the loggerFacrory

Parameters:

loggerFactory - * @throws Exception

Method Detail

addLoggerListener

public void addLoggerListener(IXARecorderResourceListener listener)

the logger is added to all instanciated Loggers

close

public void close()

Description copied from interface: IPhynixxLoggerSystemStrategy

closes the strategy including all resources

Specified by:

close in interface IPhynixxLoggerSystemStrategy<C extends IPhynixxConnection & IXADataRecorderAware>

connectionRecovering

public void connectionRecovering(IManagedConnectionEvent<C> event)

Description copied from interface: IPhynixxManagedConnectionListener

connection enters state 'recovering'

Specified by:

connectionRecovering in interface IPhynixxManagedConnectionListener<C extends IPhynixxConnection & IXADataRecorderAware>

Overrides:

connectionRecovering in class PhynixxManagedConnectionListenerAdapter<C extends IPhynixxConnection & IXADataRecorderAware>

connectionReleased

public void connectionReleased(IManagedConnectionEvent<C> event)

If a dataRecorder is found in this phase it indicates an abnormal program flow. Die Transaktion isn't terminate via commit/rollback and this connection happens to be recoverd Therefore the dataRecorder isn't close and keeps it's content to possibly be recovered

Specified by:

connectionReleased in interface IPhynixxManagedConnectionListener<C extends IPhynixxConnection & IXADataRecorderAware>

Overrides:

connectionReleased in class PhynixxManagedConnectionListenerAdapter<C extends IPhynixxConnection & IXADataRecorderAware>

Parameters:

event - current connection

connectionFreed

public void connectionFreed(IManagedConnectionEvent<C> event)

Logger will be closed. If a dataRecorder has remaining transactional data an abnormal prgram flow is detected an the data of the logger is not destroy but kept to further recovery

Specified by:

connectionFreed in interface IPhynixxManagedConnectionListener<C extends IPhynixxConnection & IXADataRecorderAware>

Overrides:

connectionFreed in class PhynixxManagedConnectionListenerAdapter<C extends IPhynixxConnection & IXADataRecorderAware>

Parameters:

event - current connection

connectionRecovered

public void connectionRecovered(IManagedConnectionEvent<C> event)

destroys the datalogger

Specified by:

connectionRecovered in interface IPhynixxManagedConnectionListener<C extends IPhynixxConnection & IXADataRecorderAware>

Overrides:

connectionRecovered in class PhynixxManagedConnectionListenerAdapter<C extends IPhynixxConnection & IXADataRecorderAware>

connectionRolledback

public void connectionRolledback(IManagedConnectionEvent<C> event)

Description copied from class: PhynixxManagedConnectionListenerAdapter

NOOP

Specified by:

connectionRolledback in interface IPhynixxManagedConnectionListener<C extends IPhynixxConnection & IXADataRecorderAware>

Overrides:

connectionRolledback in class PhynixxManagedConnectionListenerAdapter<C extends IPhynixxConnection & IXADataRecorderAware>
