Class MDCSnapshot

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
 }
