Direct Known Subclasses:

InheritableThreadLocalHoldingStrategy

public class ThreadLocalHoldingStrategy
extends ContextHoldingStrategy

A context-holding strategy that associates context-holders with threads. The holder for a thread is created by the initialHolder() method. (In some cases, it may be better to override that method to have it return null, so that the holder must be explicitly set.) More than one thread may be given the same context-holder, however this must be done with care, because some objects that use contexts frequently change their current context, and two threads doing that with the same holder could confuse each other.
