| /** |
| * 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' ) |
| * |
