getNamespaceManager

NamespaceManager getNamespaceManager()

setNamespaceManager

void setNamespaceManager(NamespaceManager nsManager)

getId

org.openrdf.model.Resource getId()

Get the identifier this Graph as a named graph.

Returns:

The identifier for this Graph or null if it has no identifier.

setId

void setId(org.openrdf.model.Resource id)

Set the identifier for this Graph as a named graph.

Parameters:

id - The identifier for this Graph

vertex

Vertex vertex()

A convenience method that creates a new Vertex with a BNode identifier.

Returns:

The newly created Vertex with a BNode identifier.

vertex

Vertex vertex(String id)

A convenience method that gets or creates a Vertex from a string IRI identifier.

Parameters:

id - The IRI for the vertex that is to be returned.

Returns:

The Vertex with the specified IRI. If no such vertex exists in this Graph, it will be created.

vertices

Collection<Vertex> vertices()

Returns the set of vertices in this Graph

vertex

Vertex vertex(org.openrdf.model.Resource id)

Create or get a Vertex with the specified id.

Parameters:

id - The identifier for the Vertex.

Returns:

The Vertex with the specified id. If no such vertex exists in this Graph, it will be created.

getVertex

Vertex getVertex(org.openrdf.model.Resource id)

Get the Vertex with the specified id.

Parameters:

id - The identifier for the Vertex that is to be returned

Returns:

The Vertex with the specified id, or null if no such Vertex exists in this Graph.

getVertex

Vertex getVertex(String id)

A convenience method that gets the Vertex with the specified id.

Parameters:

id - The identifier for the Vertex that is to be returned

Returns:

The Vertex with the specified id, or null if no such Vertex exists in this Graph.

edge

Edge edge(org.openrdf.model.Resource subject,
          org.openrdf.model.URI predicate,
          org.openrdf.model.Value object)

Add an edge to this Graph.

Parameters:

subject - The subject in the statement expressed by the edge.

predicate - The predicate in the statement expressed by the edge

object - The value in the statement expressed by the edge.

Returns:

The edge that was added to this Graph

edge

Edge edge(org.openrdf.model.Resource subject,
          org.openrdf.model.URI predicate,
          org.openrdf.model.Value object,
          org.openrdf.model.Resource context)

add

void add(Vertex vertex)

Add all the outgoing statements from the given vertex. If the object of any outgoing statement is a BNode, then recursively add its outgoing statements also.

vertex - The vertex whose outgoing statements will be added to this graph.

remove

void remove(Edge edge)

Remove the specified edge from this graph

Parameters:

edge - The edge to be removed.

remove

Parameters:

v - The vertex to be removed

remove

void remove(org.openrdf.model.Resource resource)

Parameters:

subject -

Returns:

tx

Transaction tx()

Get the Transactional view of this Graph.

Returns:

The Transactional view of this Graph, or null if the Graph is not transactional
