LevelMatchFilter

java.lang.Object
- org.apache.log4j.spi.Filter
- - org.apache.log4j.filter.LevelMatchFilter

All Implemented Interfaces:

org.apache.log4j.spi.OptionHandler
```
public class LevelMatchFilter
extends org.apache.log4j.spi.Filter
```
This is a very simple filter based on level matching.
The filter admits two options LevelToMatch and AcceptOnMatch. If there is an exact match between the value of the LevelToMatch option and the level of the LoggingEvent, then the decide(org.apache.log4j.spi.LoggingEvent) method returns Filter.ACCEPT in case the AcceptOnMatch option value is set to true, if it is false then Filter.DENY is returned. If there is no match, Filter.NEUTRAL is returned.
