Method Detail

clone

public Object clone()

Specified by:

clone in class TinkerElement

graph

public Graph graph()

Description copied from interface: Element

Get the graph that this element is within.

Specified by:

graph in interface Element

Returns:

the graph of this element

property

public <V> VertexProperty<V> property(String key)

Description copied from interface: Vertex

Get the VertexProperty for the provided key. If the property does not exist, return VertexProperty.empty(). If there are more than one vertex properties for the provided key, then throw Vertex.Exceptions.multiplePropertiesExistForProvidedKey(java.lang.String).

Specified by:

property in interface Element

Specified by:

property in interface Vertex

Type Parameters:

V - the expected type of the vertex property value

Parameters:

key - the key of the vertex property to get

Returns:

the retrieved vertex property

property

public <V> VertexProperty<V> property(VertexProperty.Cardinality cardinality,
                                      String key,
                                      V value,
                                      Object... keyValues)

Description copied from interface: Vertex

Create a new vertex property. If the cardinality is VertexProperty.Cardinality.single, then set the key to the value. If the cardinality is VertexProperty.Cardinality.list, then add a new value to the key. If the cardinality is VertexProperty.Cardinality.set, then only add a new value if that value doesn't already exist for the key. If the value already exists for the key, add the provided key value vertex property properties to it.

Specified by:

property in interface Vertex

Type Parameters:

V - the type of the value of the vertex property

Parameters:

cardinality - the desired cardinality of the property key

key - the key of the vertex property

value - The value of the vertex property

keyValues - the key/value pairs to turn into vertex property properties

Returns:

the newly created vertex property

keys

public Set<String> keys()

Description copied from interface: Element

Get the keys of the properties associated with this element. The default implementation iterators the properties and stores the keys into a HashSet.

Specified by:

keys in interface Element

Returns:

The property key set

addEdge

public Edge addEdge(String label,
                    Vertex vertex,
                    Object... keyValues)

Description copied from interface: Vertex

Add an outgoing edge to the vertex with provided label and edge properties as key/value pairs. These key/values must be provided in an even number where the odd numbered arguments are String property keys and the even numbered arguments are the related property values.

Specified by:

addEdge in interface Vertex

Parameters:

label - The label of the edge

vertex - The vertex to receive an incoming edge from the current vertex

keyValues - The key/value pairs to turn into edge properties

Returns:

the newly created edge

remove

public void remove()

Description copied from interface: Element

Removes the Element from the graph.

Specified by:

remove in interface Element

toString

public String toString()

Overrides:

toString in class Object

edges

public Iterator<Edge> edges(Direction direction,
                            String... edgeLabels)

Description copied from interface: Vertex

Gets an Iterator of incident edges.

Specified by:

edges in interface Vertex

Parameters:

direction - The incident direction of the edges to retrieve off this vertex

edgeLabels - The labels of the edges to retrieve. If no labels are provided, then get all edges.

Returns:

An iterator of edges meeting the provided specification

vertices

public Iterator<Vertex> vertices(Direction direction,
                                 String... edgeLabels)

Description copied from interface: Vertex

Gets an Iterator of adjacent vertices.

Specified by:

vertices in interface Vertex

Parameters:

direction - The adjacency direction of the vertices to retrieve off this vertex

edgeLabels - The labels of the edges associated with the vertices to retrieve. If no labels are provided, then get all edges.

Returns:

An iterator of vertices meeting the provided specification

properties

public <V> Iterator<VertexProperty<V>> properties(String... propertyKeys)

Description copied from interface: Vertex

Get an Iterator of properties where the propertyKeys is meant to be a filter on the available keys. If no keys are provide then return all the properties.

Specified by:

properties in interface Element

Specified by:

properties in interface Vertex
