A filter that 'and's the results of any number of contained filters together.
For the filter to process events, all contained filters must return Filter::ACCEPT.
If the contained filters do not return Filter::ACCEPT, Filter::NEUTRAL is returned.
If acceptOnMatch is set to true, Filter::ACCEPT is returned. If acceptOnMatch is set to false, Filter::DENY is returned.
Here is an example config that will accept only events that contain BOTH a DEBUG level AND 'test' in the message:
<appender name="STDOUT" class="org.apache.log4j.ConsoleAppender"> <filter class="org.apache.log4j.filter.AndFilter"> <filter class="org.apache.log4j.filter.LevelMatchFilter"> <param name="levelToMatch" value="DEBUG" /> <param name="acceptOnMatch" value="true" /> </filter> <filter class="org.apache.log4j.filter.StringMatchFilter"> <param name="stringToMatch" value="test" /> <param name="acceptOnMatch" value="true" /> </filter> <param name="acceptOnMatch" value="false"/> </filter> <filter class="org.apache.log4j.filter.DenyAllFilter"/> <layout class="org.apache.log4j.SimpleLayout"/> </appender>
To accept all events EXCEPT those events that contain a DEBUG level and 'test' in the message: change the AndFilter's acceptOnMatch param to false and remove the DenyAllFilter
NOTE: If you are defining a filter that is only relying on logging event content (no external or filter-managed state), you could opt instead to use an ExpressionFilter with one of the following expressions:
LEVEL == DEBUG && MSG ~= 'test' or ! ( LEVEL == DEBUG && MSG ~= 'test' )
| AndFilter | ( | ) |
| void addFilter | ( | const log4cxx::spi::FilterPtr & | filter | ) |

If the decision is DENY, then the event will be dropped. If the decision is NEUTRAL, then the next filter, if any, will be invoked. If the decision is ACCEPT then the event will be logged without consulting with other filters in the chain.
