    • Method Detail

      • put

        void put​(String key,
                 String val)
        Put a context value (the val parameter) as identified with the key parameter into the current thread's context map. The key parameter cannot be null. The val parameter can be null only if the underlying implementation supports it.

        If the current thread does not have a context map it is created as a side effect of this call.

      • get

        String get​(String key)
        Get the context identified by the key parameter. The key parameter cannot be null.
        Returns:
        the string value identified by the key parameter.
      • remove

        void remove​(String key)
        Remove the the context identified by the key parameter. The key parameter cannot be null.

        This method does nothing if there is no previous value associated with key.

      • clear

        void clear()
        Clear all entries in the MDC.
      • getCopyOfContextMap

        Map<String,​StringgetCopyOfContextMap()
        Return a copy of the current thread's context map, with keys and values of type String. Returned value may be null.
        Returns:
        A copy of the current thread's context map. May be null.
        Since:
        1.5.1
      • setContextMap

        void setContextMap​(Map<String,​String> contextMap)
        Set the current thread's context map by first clearing any existing map and then copying the map passed as parameter. The context map parameter must only contain keys and values of type String.
        Parameters:
        contextMap - must contain only keys and values of type String
        Since:
        1.5.1
