java.lang.Object
  org.x4juli.global.spi.location.StackTraceElementExtractor

public class StackTraceElementExtractor

extends java.lang.Object

A faster extractor based on StackTraceElements introduced in JDK 1.4. The present code uses reflection. Thus, it should compile on all platforms.

Logging API as a whole was originally done for Apache log4j. Juli is a port of main parts of that to complete the Java Logging APIs. All credits for initial idea, design, implementation, documentation belong to the log4j crew. This file was originally published by Martin Schulz, Ceki Gülcü.
