| 35 | * A filter that 'and's the results of any number of contained filters together.

|

| 37 | * For the filter to process events, all contained filters must return Filter::ACCEPT.

| 41 | * If acceptOnMatch is set to true, Filter::ACCEPT is returned.

---|
| 43 | *
|
---|
| 44 | * Here is an example config that will accept only events that contain BOTH
|
---|
| 45 | * a DEBUG level AND 'test' in the message:

|

| 47 | *<appender name="STDOUT" class="org.apache.log4j.ConsoleAppender">

|
---|
| 61 | *</appender>
|
---|
| 62 | *
|
---|
| 63 | * To accept all events EXCEPT those events that contain a
|
---|
| 64 | * DEBUG level and 'test' in the message:
|
---|
| 65 | * change the AndFilter's acceptOnMatch param to false and remove the DenyAllFilter
|
---|
| 66 | *
|
---|
| 67 | * NOTE: If you are defining a filter that is only relying on logging event content
|
---|
| 68 | * (no external or filter-managed state), you could opt instead
|
---|
| 69 | * to use an ExpressionFilter with one of the following expressions:
|
---|
| 70 | *
|
---|
| 71 | * LEVEL == DEBUG && MSG ~= 'test'
|
---|
| 72 | * or
|
---|
| 73 | * ! ( LEVEL == DEBUG && MSG ~= 'test' )
