Apache Tomcat 6.0.41

org.apache.tomcat.util.threads
Class ThreadWithAttributes

java.lang.Object
  extended by java.lang.Thread
      extended by org.apache.tomcat.util.threads.ThreadWithAttributes
All Implemented Interfaces:
java.lang.Runnable

public class ThreadWithAttributes
extends java.lang.Thread

Special thread that allows storing of attributes and notes. A guard is used to prevent untrusted code from accessing the attributes. This avoids hash lookups and provide something very similar with ThreadLocal ( but compatible with JDK1.1 and faster on JDK < 1.4 ). The main use is to store 'state' for monitoring ( like "processing request 'GET /' ").
