- Method Detail
  - setUrl
```
public static void setUrl(@Nullable
                          String url)
```
    Sets the 'url' value in the logging context. Does nothing if url is null.
  - setUserName
```
public static void setUserName(@Nullable
                               String userName)
```
    Sets the 'userName' value in the logging context. Sets it to 'anonymous' if userName is null.
  - getUserName
```
public static String getUserName()
```
    Returns the currently mapped 'userName' value from the context, or null if none has been set.
  - setReferer
```
public static void setReferer(@Nullable
                              String referer)
```
    Sets the 'referer' value in the logging context. Does nothing if referer is null.
  - put
```
public static void put(String key,
                       Object value)
```
    Sets the value associated with the key in the logging context, overwriting any existing value. The value can either be a String, object equivalent of a primitive type or a Jsonable.
    Code which calls to this method should remove the context information by calling remove(java.lang.String...) with the same key in a finally block.
    
    See Also:
    
    MDC.put(java.lang.String, java.lang.Object)
  - remove
```
public static void remove(String... keys)
```
    Removes any value associated with the keys in the logging context.
  - isEmpty
```
public static boolean isEmpty()
```
    Returns true if the logging context has been initialised and has data in it, otherwise false.
  - getContext
```
public static Map<String,Object> getContext()
```
    Returns an immutable copy of the underlying logging context map.
  - clear
```
public static void clear()
```
    Removes all keys from the logging context which are managed by this class. Anything which has been added by a call to put(java.lang.String, java.lang.Object) needs to be removed by calling remove(java.lang.String...) with the same key.
  - clearAll
```
public static void clearAll()
```
    Clears all MDC information on the current thread. Normally used to clear nested MDC information on a new thread.
  - executeWithContext
```
public static void executeWithContext(Map<String,Object> context,
                                      Runnable runnable)
```
    Execute Runnable with MDC context that is removed once the runnable returns.
    
    Parameters:
    
    context - context to have in MDC while runnable is executed. The values can either be a String, object equivalent of a primitive type or a Jsonable.
    
    runnable - runnable to execute
