Method Detail

put

public static void put(String key,
                       String val)

Minor improvement over MDC.put(String, String). Specifically, it:

• tests if there already is an entry for the given key (to detect forgotten remove, instead of overwriting)
• does not accept null as val

Throws:

IllegalArgumentException - if val is value is already set (and was previously not MDC.remove(String))

putRunRemove

public static void putRunRemove(String key,
                                String val,
                                Runnable runnable)

put(String, String) a key/val into the MDC, runs the provided Runnable, and (ensure that) the given key is MDC.remove(String)'d (even if there was an exception).

putRunRemove

public static void putRunRemove(MDCEntry entry,
                                Runnable runnable)

putRunRemove

public static void putRunRemove(Map<String,String> keysValues,
                                Runnable runnable)

put(String, String) each key/val of the passed Map into the MDC, runs the provided Runnable, and (ensure that) the all keys of the Map are MDC.remove(String)'d (even if there was an exception).

putRunRemove

public static void putRunRemove(Runnable runnable,
                                MDCEntry... keysValues)
