[logback-dev] More than one filter in Appender

[Ceki Gulcu]

Sure. Just declare multiple filters. Example:

   <appender class="...">
     <filter class="..."/>
     </filter>
     <filter class="..."/>
     </filter>
   </appender>

If you look at the AppenderBase base class in logback-core [1], there
is a method called addFilter(Filter). Joran, logback's configuration
framework, can deal with getters and setters as well as "adder"
methods. See the section entitled "Collection of Properties" in the
logback manual [2]. Essentially, the "adder" convention is useful for
dealing with a collection of properties, such as filters, instead of
just a single property.
