Detailed Description
Location information is usually specified at the appender level - all events associated with an appender either create and parse stack traces or they do not.
This is an expensive operation and in some cases not needed for all events associated with an appender.
This filter creates event-level location information only if the provided expression evaluates to true.
For information on expression syntax, see org.apache.log4j.rule.ExpressionRule
Constructor & Destructor Documentation
◆ LocationInfoFilter()
| log4cxx::filter::LocationInfoFilter::LocationInfoFilter | ( | ) |
Member Function Documentation
◆ activateOptions()
|
virtual |
Activate the options that were previously set with calls to option setters.
This allows to defer activiation of the options until all options have been set. This is required for components which have related options that remain ambigous until all are set.
For example, the FileAppender has the File and Append options both of which are ambigous until the other is also set.
Implements log4cxx::spi::OptionHandler.
◆ decide()
|
virtual |
If this event does not already contain location information, evaluate the event against the expression.
If the expression evaluates to true, generate a LocationInfo instance by creating an exception and set this LocationInfo on the event.
Returns log4cxx::spi::Filter#NEUTRAL
Implements log4cxx::spi::Filter.
