--------------------------------------
Summary: Javadoc for AbstractFilter wrong?
Key: LOG4J2-1154
URL: https://issues.apache.org/jira/browse/LOG4J2-1154
Project: Log4j 2
Issue Type: Documentation
Components: Filters
Affects Versions: 2.4
Reporter: Philipp Knobel
The class org.apache.logging.log4j.core.Filter has as javadoc for the filter
methods just the description: *Filter an event.*
The org.apache.logging.log4j.core.filter.AbstractFilter has as description for
three of the filter methods:
* Appender Filter method. The default returns NEUTRAL.*
could you clarify when each of these will be called?
And the last one *filter(LogEvent)* has as decription *Context Filter method.
The default returns NEUTRAL.*
But this method isn't called, when I configure the filter as context filter.
My config looks like:
{code}
<configuration name="test" packages="my.package">
<MyFilter/>
<Appenders>
<Console name="Console" target="SYSTEM_OUT">
<PatternLayout
pattern="m%n"
charset="UTF-8"/>
</Console>
</Appenders>
<Loggers>
<root level="DEBUG">
<AppenderRef ref="Console"/>
</root>
</Loggers>
</configuration>
{code}
And btw., do I understand it correctly that each logger calls all Context
Filter as well? So that the only benefit of a context filter is that it's
shared acrossed Logger, but not actually allowing reducing the invocation count
of the filter as if it was defined for each Logger?
