org.aksw.jenax.io.kryo.jena.GenericNodeSerializerCustom

Direct Known Subclasses:

DefaultNodeSerializer

public class GenericNodeSerializerCustom
extends com.esotericsoftware.kryo.Serializer<org.apache.jena.graph.Node>

A node serializer using a custom (i.e. non-standard) format for intermediate serialization. This class was created in order to allow processing of invalid RDF data. Examples include IRIs with white spaces or even worse IRIs with angular brackets which would result in a non-parsable turtle serialization.
