Exploiting ThreadLocal to enhance scalability Hits: 35 ***** 0.0 The ThreadLocal class       appeared with little fanfare       in version 1.2 of the Java       platform. While support for       thread-local variables has       long been a part of many       threading facilities, such       as the Posix pthreads       facility, the initial design       of the Java Threads       API lacked this useful       feature. Further, the       initial implementation was       quite inefficient. For these       reasons, ThreadLocal gets       relatively little attention,       but it can be very handy for       simplifying the development       of thread-safe concurrent       programs. This article       examines ThreadLocal and       offers tips for exploiting       its power.       Date: Oct, 17 2001
