[noreply.seb at qos.ch]

Author: seb
Date: Mon Jan  8 11:06:45 2007
New Revision: 1168

Added:
   logback/trunk/logback-classic/src/main/java/ch/qos/logback/classic/filter/LevelFilter.java
   logback/trunk/logback-classic/src/main/java/ch/qos/logback/classic/filter/ThresholdFilter.java

Log:
Added ThresholdFilter class and modified LevelFilter class. The latter now acts as a configurable
filter to allow or deny a specific given level. ThresholdFilter allows any logging events whose level is
higher or equals to its configured level.

Added: logback/trunk/logback-classic/src/main/java/ch/qos/logback/classic/filter/LevelFilter.java
