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

Usually filters options become active when set.

We provide a

default do-nothing implementation for convenience.

Reimplemented from Filter.

const [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
