public class ExtensiblePatternFormatter
extends Object
implements Formatter

A refactoring of org.apache.log.format.PatternFormatter that can be extended. This formater formats the LogEntries according to a input pattern string. The format of each pattern element can be %[+|-]#.#{field:subformat} The +|- indicates left or right justify. The #.# indicates the minimum and maximum size of output. 'field' indicates which field is to be output and must be one of properties of LogEvent 'subformat' indicates a particular subformat and is currently unused.
