## Member Function Documentation

void addRef | ( |  | ) | const
| virtual

Reimplemented from ObjectImpl.

virtual bool isTriggeringEvent | ( | Appender * | appender,
|  | const log4cxx::spi::LoggingEventPtr & | event,
|  | const LogString & | filename,
|  | size_t | fileLength
| ) |  |
| pure virtual

Determines if a rollover may be appropriate at this time.

If true is returned, RolloverPolicy.rollover will be called but it can determine that a rollover is not warranted.

Parameters

  appender | A reference to the appender.
  event | A reference to the currently event.
  filename | The filename for the currently active log file.
  fileLength | Length of the file in bytes.

Returns
  true if a rollover should occur.

Implemented in TimeBasedRollingPolicy, FilterBasedTriggeringPolicy, SizeBasedTriggeringPolicy, and ManualTriggeringPolicy.

void releaseRef | ( |  | ) | const
| virtual

Reimplemented from ObjectImpl.
