All Implemented Interfaces:

Serializable, Iterable<org.slf4j.Marker>, org.slf4j.Marker

public class DeferredLogstashMarker
extends LogstashMarker

A LogstashMarker that defers the creation of another LogstashMarker until the first time it is encoded.

Encoding (and therefore the deferred marker creation) can potentially take place on another thread if an async appender (e.g. AsyncAppender or AsyncDisruptorAppender) is used.

The deferred value will only be calculated once. The single value supplied by the supplier will be reused every time the marker is written. For example, if multiple appenders use a logstash encoder, the supplier will be invoked when the first appender encodes the marker. That same supplied value will be used when the next appender encodes the marker.
