All Implemented Interfaces:
Serializable
public class NodeCustom<T> extends org.apache.jena.graph.Node_Ext<T>
A Node implementation that can hold an arbitrary object as its payload. This class provides static utility methods to find NodeCustom instances in expressions and transform those expressions into new ones.
