Method Detail

logSuccessful

public void logSuccessful(CommandMessage<?> command,
                          Object returnValue,
                          List<EventMessage> events)

Writes a success entry to the audit logs.

This method may be invoked in the thread dispatching the command. Therefore, considering writing asynchronously when the underlying mechanism is slow.

This implementation does nothing.

Specified by:

logSuccessful in interface AuditLogger

Parameters:

command - The command that has been handled

returnValue - The return value of the command handler

events - The events that were generated during command handling

logFailed

public void logFailed(CommandMessage<?> command,
                      Throwable failureCause,
                      List<EventMessage> events)

Writes a failure entry to the audit logs. The given list of events may contain events. In that case, these event may have been stored in the events store and/or published to the event bus.

This method may be invoked in the thread dispatching the command. Therefore, considering writing asynchronously when the underlying mechanism is slow.

This implementation does nothing.

Specified by:

logFailed in interface AuditLogger

Parameters:

command - The command being executed

failureCause - The cause of the rollback. May be null if the rollback was not caused by an exception
