Package Summary Overview Summary

### class:InheritableThreadLocal [NONE]
Type Parameters: `T` - the type of the inheritable thread local's value public class InheritableThreadLocal<T>extends ThreadLocal<T> This class extends `ThreadLocal` to provide inheritance of values from parent thread to child thread: when a child thread is created, the child receives initial values for all inheritable thread-local variables for which the parent has values. Normally the child's values will be identical to the parent's; however, the child's value can be made an arbitrary function of the parent's by overriding the `childValue` method in this class. Inheritable thread-local variables are used in preference to ordinary thread-local variables when the per-thread-attribute being maintained in the variable (e.g., User ID, Transaction ID) must be automatically transmitted to any child threads that are created. Note: During the creation of a new `thread`, it is possible to opt out of receiving initial values for inheritable thread-local variables. Since: 1.2 See Also: `ThreadLocal` `Thread.Builder.inheritInheritableThreadLocals(boolean)`PREVIEW
