## Detailed Description

FilterBasedTriggeringPolicy determines if rolling should be triggered by evaluating the current message against a set of filters.

Unless a filter rejects a message, a rolling event will be triggered.

## Constructor & Destructor Documentation

FilterBasedTriggeringPolicy | ( |  | ) |

Creates a new FilterBasedTriggeringPolicy.

virtual ~FilterBasedTriggeringPolicy | ( |  | ) |
| virtual

## Member Function Documentation

void activateOptions | ( | log4cxx::helpers::Pool & |  | ) |
| virtual

Prepares the instance for use.

Implements OptionHandler.

void addFilter | ( | const log4cxx::spi::FilterPtr & | newFilter | ) |

Add a filter to end of the filter list.

Parameters

  newFilter | filter to add to end of list.

void clearFilters | ( |  | ) |

Clear the filters chain.

log4cxx::spi::FilterPtr& getFilter | ( |  | ) |

Returns the head Filter.

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

Implements TriggeringPolicy.

void setOption | ( | const LogString & | option,
|  | const LogString & | value
| ) |  |
| virtual

Set `option` to `value`.

The handling of each option depends on the OptionHandler instance. Some options may become active immediately whereas other may be activated only when activateOptions is called.

Implements OptionHandler.
