```
public class MDCLoggingContext
extends Object
```
Set's per thread context info for logging. Nested calls will use the top level parent for all context. The first caller always owns the context until it calls clear(). Always call setCore(SolrCore) or setCoreDescriptor(CoreContainer, CoreDescriptor) and then clear() in a finally block.

All Methods Static Methods Concrete Methods
Modifier and Type	Method	Description
`static void`	`clear()`	Call this after `setCore(SolrCore)` or `setCoreDescriptor(CoreContainer, CoreDescriptor)` in a finally.
`static String`	`getNodeName()`
`static String`	`getTraceId()`
`static void`	`reset()`	Resets to a cleared state.
`static void`	`setCollection(String collection)`
`static void`	`setCore(SolrCore core)`	Sets multiple information from the params.
`static void`	`setCoreDescriptor(CoreContainer coreContainer, CoreDescriptor cd)`	Sets multiple information from the params.
`static void`	`setCoreName(String core)`
`static void`	`setNode(String node)`
`static void`	`setNode(CoreContainer cc)`
`static void`	`setReplica(String replica)`
`static void`	`setShard(String shard)`
`static void`	`setTracerId(String traceId)`

Sets multiple information from the params. REMEMBER TO CALL clear() in a finally!
