PaxContext (OPS4J Pax Logging - API 2.3.1 API)

java.lang.Object
- org.ops4j.pax.logging.PaxContext

```
public class PaxContext
extends Object
```
The MDC class that provides mapped diagnostic contexts. A Mapped Diagnostic Context, or MDC in short, is an instrument for distinguishing interleaved log output from different sources. Log output is typically interleaved when a server handles multiple clients near-simultaneously. The MDC is managed on a per thread basis. A child thread automatically inherits a copy of the mapped diagnostic context of its parent (with normal InheritableThreadLocal child inherits the same references). That behavior can be switched off by setting the system property org.ops4j.pax.logging.threadContextMapInheritable to false (default is true). The MDC class requires JDK 1.2 or above. Under JDK 1.1 the MDC will always return empty values but otherwise will not affect or harm your application.

Since:

1.2
