Method Detail

stopTransaction

public void stopTransaction(com.tinkerpop.blueprints.TransactionalGraph.Conclusion conclusion)

Specified by:

stopTransaction in interface com.tinkerpop.blueprints.TransactionalGraph

getFeatures

public com.tinkerpop.blueprints.Features getFeatures()

Specified by:

getFeatures in interface com.tinkerpop.blueprints.Graph

addVertex

public TitanVertex addVertex(Object id)

Creates a new vertex in the graph with the given vertex id. Note, that an exception is thrown if the vertex id is not a valid Titan vertex id or if a vertex with the given id already exists. Only accepts long ids - all others are ignored.

Custom id setting must be enabled via the configuration option GraphDatabaseConfiguration.ALLOW_SETTING_VERTEX_ID.

Use TitanId.toVertexId(long) to construct a valid Titan vertex id from a user id.

Specified by:

addVertex in interface com.tinkerpop.blueprints.Graph

Parameters:

id - vertex id of the vertex to be created

Returns:

New vertex

getVertex

public TitanVertex getVertex(Object id)

addEdge

public TitanEdge addEdge(TitanVertex outVertex,
                TitanVertex inVertex,
                String label)

Description copied from interface: TitanTransaction

Creates a new edge connecting the specified vertices.

Creates and returns a new TitanEdge with given label connecting the vertices in the order specified.
Automatically creates the edge label if it does not exist and automatic creation of types is enabled. Otherwise, this method with throw an IllegalArgumentException.

Specified by:

addEdge in interface TitanTransaction

Parameters:

outVertex - outgoing vertex of the edge

inVertex - incoming vertex of the edge

label - label of the edge to be created

Returns:

new edge

addProperty

public TitanProperty addProperty(TitanVertex vertex,
                        String key,
                        Object attribute)

Description copied from interface: TitanTransaction

Creates a new property for the given vertex and key with the specified value.

Creates and returns a new TitanProperty with specified property key and the given object being the value.
Automatically creates the property key if it does not exist and automatic creation of types is enabled. Otherwise, this method with throw an IllegalArgumentException.

Specified by:

addProperty in interface TitanTransaction

Parameters:

vertex - vertex for which to create the property

key - key of the property to be created

attribute - value of the property to be created

Returns:

new property
