Improve performance by removing StringBuffer where possible -----------------------------------------------------------

Key: LBCLASSIC-111 URL: http://jira.qos.ch/browse/LBCLASSIC-111 Project: logback-classic Issue Type: Bug Affects Versions: 0.9.15 Environment: any Reporter: Rick Beton Assignee: Logback dev list Priority: Minor

StringBuffer is used in some local variables. The newer StringBuilder alternative will improve the performance slightly in such cases. E.g.in FileNamePattern public String convert(Object o) { Converter<Object> p = headTokenConverter; StringBuffer buf = new StringBuffer(); while (p != null) { buf.append(p.convert(o)); p = p.getNext(); } return buf.toString(); } should change to use StringBuilder buf = new StringBuilder();
