Class JsonRenderer.FieldConsumer

java.lang.Object

com.yahoo.search.rendering.JsonRenderer.FieldConsumer

All Implemented Interfaces:

com.yahoo.container.logging.TraceRenderer.FieldConsumer, Hit.RawUtf8Consumer, BiConsumer<String,Object>

Enclosing class:

JsonRenderer

public static class JsonRenderer.FieldConsumer
extends Object
implements Hit.RawUtf8Consumer, com.yahoo.container.logging.TraceRenderer.FieldConsumer

Received callbacks when fields of hits are encountered. This instance is reused for all hits of a Result since we are in a single-threaded context and want to limit object creation.
