Class ThreadContext

java.lang.Object

org.exoplatform.container.component.ThreadContext

public class ThreadContext
extends Object

This component contains all the variables of type ThreadLocal hold by a ThreadContextHolder This component has not been designed to be thread safe so ensure that you create a new instance each time you use it. Moreover for security reason, when the SecurityManager is installed we check the RuntimePermission manageThreadLocal only within the constructor of a ThreadContext.
