    public final class LogMF

extends LogXF

This class provides parameterized logging services using the pattern syntax of java.text.MessageFormat. Message formatting is only performed when the request exceeds the threshold level of the logger. When the pattern only contains literal text and default conversion patterns (that is "{0}" and similar) a simple fast compatible formatter is used. If the pattern contains more complex conversion patterns, formatting will be delegated to java.text.MessageFormatter which can be substantially slower.
