Class MarkerManager.Log4jMarker

  • All Implemented Interfaces:
    Serializable, Marker, StringBuilderFormattable
    Enclosing class:
    MarkerManager

    public static class MarkerManager.Log4jMarker
extends Object
implements Marker, StringBuilderFormattable
    Consider this class private, it is only public to satisfy Jackson for XML and JSON IO.

    The actual Marker implementation.

    Internal note: We could make this class package private instead of public if the class org.apache.logging.log4j.core.jackson.MarkerMixIn is moved to this package and would of course stay in its current module.
