Package org.apache.tinkerpop.gremlin.structure.io.graphson

Class GraphSONMapper

java.lang.Object

org.apache.tinkerpop.gremlin.structure.io.graphson.GraphSONMapper

All Implemented Interfaces:

Mapper<org.apache.tinkerpop.shaded.jackson.databind.ObjectMapper>

public class GraphSONMapper
extends Object
implements Mapper<org.apache.tinkerpop.shaded.jackson.databind.ObjectMapper>

An extension to the standard Jackson ObjectMapper which automatically registers the standard GraphSONModule for serializing Graph elements. This class can be used for generalized JSON serialization tasks that require meeting GraphSON standards.

Graph implementations providing an IoRegistry should register their SimpleModule implementations to it as follows:

 
 public class MyGraphIoRegistry extends AbstractIoRegistry {
   public MyGraphIoRegistry() {
     register(GraphSONIo.class, null, new MyGraphSimpleModule());
   }
 }
