public class InheritableThreadLocal<T> extends ThreadLocal<T>
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.
|Constructor and Description|
