Class ThreadContextDataInjector

java.lang.Object

org.apache.logging.log4j.core.impl.ThreadContextDataInjector

public class ThreadContextDataInjector
extends Object

ThreadContextDataInjector contains a number of strategies for copying key-value pairs from the various ThreadContext map implementations into a StringMap. In the case of duplicate keys, thread context values overwrite configuration Property values.

These are the default ContextDataInjector objects returned by the ContextDataInjectorFactory.

Since:

2.7
