Class AndFilter

java.lang.Object
org.apache.log4j.spi.Filter
org.apache.log4j.filter.AndFilter
All Implemented Interfaces:
org.apache.log4j.spi.OptionHandler, org.apache.log4j.xml.UnrecognizedElementHandler
public class AndFilter extends org.apache.log4j.spi.Filter implements org.apache.log4j.xml.UnrecognizedElementHandler
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: 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 invalid input: '&'invalid input: '&' MSG ~= 'test' or ! ( LEVEL == DEBUG invalid input: '&'invalid input: '&' MSG ~= 'test' ) XML configuration of this filter requires use of either log4j 1.2.15 or later or org.apache.log4j.rolling.DOMConfigurator.
