MDCSnapshot (Solr 9.0.0 core API)

java.lang.Object
- org.apache.solr.logging.MDCSnapshot

All Implemented Interfaces:

Closeable, AutoCloseable
```
public final class MDCSnapshot
extends Object
implements Closeable
```
Takes a 'snapshot' of the current MDC context map which is restored on (auto) close. This can be used to ensure that no MDC values set (or overridden) inside of call stack will "leak" beyond that call stack.
```
 try (var mdcSnapshot = MDCSnapshot.create()) {
   assert null != mdcSnapshot; // prevent compiler warning

   // ... arbitrary calls to MDC methods
 }
 
```
