public class ExtendedPatternFormatter

extends PatternFormatter

Formatter especially designed for debugging applications. This formatter extends the standard PatternFormatter to add two new possible expansions. These expansions are %{method} and %{thread}. In both cases the context map is first checked for values with specified key. This is to facilitate passing information about caller/thread when threads change (as in AsyncLogTarget). They then attempt to determine appropriate information dynamically.
