@FunctionalInterface public interface ThreadContextSnapshot
The captured context represented by this snapshot can be applied to any number of threads, including concurrently.
Any state that is associated with context applied to a thread should
be kept, not within the snapshot, but within the distinct
ThreadContextRestorer instance that this
ThreadContextSnapshot creates each time it is applied
to a thread.
ThreadContextRestorerinstance tracks the context's life cycle, including any state that is associated with it or that is necessary for restoring the previous context.
For each invocation of this method, the Jakarta EE Product Provider
must invoke the corresponding
method exactly once, such that the previous context is restored
on the thread. If the Jakarta EE Product Provider sequentially begins
ThreadContextRestorer instances on a thread,
it must invoke the corresponding
endContext methods in reverse
