org.apache.jena.graph.Node

org.apache.jena.graph.Node_Graph

All Implemented Interfaces:

Serializable

public class Node_Graph
extends Node

RDF Graphs as RDF terms.

Beware that equality and hashCode are defined by object identity, not graph same-triples nor isomorphism.

For experimentation. Otherwise, unsupported.

Method Details

isNodeGraph

public boolean isNodeGraph()

Description copied from class: Node

Answer true iff this node is an "graph node" (N3 formula). This is not related to named graphs.

Overrides:

isNodeGraph in class Node

getGraph

public Graph getGraph()

Description copied from class: Node

Get the graph for a graph term (N3 formula), otherwise die horribly

Overrides:

getGraph in class Node

visitWith

public Object visitWith(NodeVisitor v)

Description copied from class: Node

Visit a Node and dispatch on it to the appropriate method from the NodeVisitor v.

Specified by:

visitWith in class Node

Parameters:

v - the visitor to apply to the node

Returns:

the value returned by the applied method

hashCode

public int hashCode()

Overrides:

hashCode in class Node

equals

public boolean equals(Object o)

Description copied from class: Node

Nodes only equal other Nodes that have equal labels.

Specified by:

equals in class Node

isConcrete

public boolean isConcrete()

Description copied from class: Node

Answer true iff this node is concrete, ie not variable, ie URI, blank, or literal.

Specified by:

isConcrete in class Node
