Constructors

Modifier	Constructor and Description
protected	JournalRecoveryLog(Map<String,String> parameters, String role, ServerInterface server) Concrete sub-classes must implement this constructor.

Method Summary

Methods

Modifier and Type	Method and Description
static JournalRecoveryLog	getInstance(Map<String,String> parameters, String role, ServerInterface server) Create an instance of the proper JournalRecoveryLog child class, as determined by the server parameters.
void	log(ConsumerJournalEntry journalEntry) Format a journal entry for writing to the logger.
abstract void	log(String message) Concrete sub-classes should probably synchronize this method, since it can be called either from the JournalConsumerThread or from the Server.
protected void	log(String message, Writer writer) Concrete sub-classes call this method to perform the final formatting if a log entry.
void	logHeaderInfo(Map<String,String> parameters) Concrete sub-classes should call this method from their constructor, or as soon as the log is ready for writing.
abstract void	shutdown() Concrete sub-classes should probably synchronize this method, since it can be called either from the JournalConsumerThread or from the Server.
void	shutdown(String message)

Constructor Detail

JournalRecoveryLog

protected JournalRecoveryLog(Map<String,String> parameters,
                  String role,
                  ServerInterface server)
                      throws ModuleInitializationException

Concrete sub-classes must implement this constructor. Checks the server parameters to find out what Logging Level to use - default is Low.

Throws:

ModuleInitializationException

Method Detail

getInstance

public static JournalRecoveryLog getInstance(Map<String,String> parameters,
                             String role,
                             ServerInterface server)
                                      throws ModuleInitializationException

Create an instance of the proper JournalRecoveryLog child class, as determined by the server parameters.

Throws:

ModuleInitializationException

log

public abstract void log(String message)

Concrete sub-classes should probably synchronize this method, since it can be called either from the JournalConsumerThread or from the Server.

shutdown

public abstract void shutdown()

Concrete sub-classes should probably synchronize this method, since it can be called either from the JournalConsumerThread or from the Server. For the same reason, they should also provide for the possibility that it will be called multiple times, or that a call to log() will happen after the call to shutdown().

shutdown

public void shutdown(String message)

logHeaderInfo

public void logHeaderInfo(Map<String,String> parameters)

Concrete sub-classes should call this method from their constructor, or as soon as the log is ready for writing.

log

public void log(ConsumerJournalEntry journalEntry)

Format a journal entry for writing to the logger. Take logging level into account.

log

protected void log(String message,
       Writer writer)

Concrete sub-classes call this method to perform the final formatting if a log entry.
