Class ThreadContext

java.lang.Object

org.tinylog.ThreadContext

public final class ThreadContext
extends Object

Thread-based mapped diagnostic context for enriching log entries with additional values. A stored value is only visible for the thread, in which this value has been set, and its child threads.

If values will be stored by a thread from a thread pool, clear() should be called before putting the thread back to the pool.
