All Implemented Interfaces:

java.io.Serializable, org.slf4j.Marker

public class ObjectAppendingMarker
extends SingleFieldAppendingMarker

A marker that converts an Object into an appropriate JSON type (number, string, object, array) and writes it to the logstash json event under a given fieldName.

For example, to append a string field, use a String object as the object. To append a numeric field, use a Number object as the object. To append an array field, use an array as the object. To append an object field, use some other Object as the object.

An ObjectMapper is used to convert/write the value, so as long as the ObjectMapper can convert the object, you're good.
