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

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:
newFilterfilter to add to end of list.
void clearFilters ( )

Clear the filters chain.

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:
appenderA reference to the appender.
eventA reference to the currently event.
filenameThe filename for the currently active log file.
fileLengthLength 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.
