      • setNodeSerializer

        public static void setNodeSerializer​(java.util.function.Function<Node,​java.lang.Object> writeReplaceFunction)
        Set the node serializer replacement function. This is a function called by Node.writeReplace during the Serializable process. The return is an object used in place of Node for the serialization. 
         ANY-ACCESS-MODIFIER Object writeReplace() throws ObjectStreamException;

        The returned object must provide 

         ANY-ACCESS-MODIFIER Object readResolve() throws ObjectStreamException;

        where "Object" is a Node.

      • getNodeSerializer

        public static java.util.function.Function<Node,​java.lang.Object> getNodeSerializer()
        Return the current node serializer replacement function.

      • setTripleSerializer

        public static void setTripleSerializer​(java.util.function.Function<Triple,​java.lang.Object> writeReplaceFunction)
        Set the triple serializer replacement function. This is a function called by Triple.writeReplace during the Serializable process. The return is an object used in place of Triple for the serialization. 
         ANY-ACCESS-MODIFIER Object writeReplace() throws ObjectStreamException;
