public class MapEntriesAppendingMarker
extends LogstashMarker

A marker that appends the entries from a map into the logstash json event. The keys are converted to a String via Object.toString(), and used as the field names. The values are converted using an ObjectMapper.

For example, if the map contains is

 name1= a String "value1",
     name2= an Integer 5,
     name3= an array containing [1, 2, 3],
     name4= a map containing { name5=6 }
 
 

Then the name1, name2, name3, name4 fields will be added to the json for the logstash event.

For example:

 {@code
 {

Version:

: 1, name1 : "value1", name2 : 5, name3 : [1, 2, 3], name4 : { name5 : 6 } }
