Class PatternFormatter

java.lang.Object
  extended by org.jivesoftware.util.log.format.PatternFormatter
All Implemented Interfaces:
Formatter
Direct Known Subclasses:
ExtendedPatternFormatter

public class PatternFormatter
extends Object
implements Formatter

This formater formats the LogEvents according to a input pattern string.

The format of each pattern element can be %[+|-][#[.#]]{field:subformat}.

A simple example of a typical PatternFormatter format:

%{time} %5.5{priority}[%-10.10{category}]: %{message}
 

This format string will format a log event printing first time value of of log event with out size restriction, next priority with minum and maximum size 5, next category right justified having minmum and maximum size of 10, at last the message of the log event without size restriction.

A formatted sample message of the above pattern format:

1000928827905 DEBUG [     junit]: Sample message
