Kieker 1.9

kieker.common.logging
Class LogImplWebguiLogging

java.lang.Object
  extended by kieker.common.logging.LogImplWebguiLogging
All Implemented Interfaces:
Log

public final class LogImplWebguiLogging
extends Object
implements Log

This is a simple logger for the Kieker WebGUI. It stores the log messages within a buffer of a static size. If the buffer is full, the oldest entry will be removed for new entries. As the entries have to be accessible from outside, the queues are stored statically.
