[noreply.seb at qos.ch]

Author: seb

New Revision: 1144

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

Log:
Added a LevelFilter that works much like the appender threshold in log4j
It returns the ACCEPT value for events whose level is equal or greater to the user provided level, and DENY otherwise.
