Class Overview
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.

T
childValue
(T parentValue)
Computes the initial value of this thread-local variable for the child
thread given the parent thread's value. Called from the parent thread when
creating a child thread. The default implementation returns the parent
thread's value.
Parameters
parentValue
| the value of the variable in the parent thread. |
Returns
- the initial value of the variable for the child thread.
