- java.lang.ThreadLocal

public class InheritableThreadLocal extends ThreadLocal

A thread-local variable whose value is passed from parent to child thread. By default, the value of an inheritable thread-local variable of a child thread is initialized with the value of the parent thread's variable at thread creation time. However, subclasses may override {code #childValue(Object)} to provide an arbitrary function for passing the value of a parent's thread-local variable to the child's thread-local variable.
