Constructor Detail

InMemoryEdge

public InMemoryEdge(InMemoryGraph graph,
                    String id,
                    InMemoryTableEdge inMemoryTableElement,
                    FetchHints fetchHints,
                    Long endTime,
                    Authorizations authorizations)

Method Detail

getLabel

public String getLabel()

Description copied from interface: Edge

The edge label.

Specified by:

getLabel in interface Edge

Specified by:

getLabel in interface EdgeElementLocation

getVertexId

public String getVertexId(Direction direction)

Description copied from interface: Edge

Get the attach vertex id on either side of the edge.

Specified by:

getVertexId in interface Edge

Specified by:

getVertexId in interface EdgeElementLocation

Parameters:

direction - The side of the edge to get the vertex id from (IN or OUT).

Returns:

The id of the vertex.

getVertex

public Vertex getVertex(Direction direction,
                        Authorizations authorizations)

Description copied from interface: Edge

Get the attach vertex on either side of the edge.

Specified by:

getVertex in interface Edge

Parameters:

direction - The side of the edge to get the vertex from (IN or OUT).

Returns:

The vertex.

getOtherVertexId

public String getOtherVertexId(String myVertexId)

Description copied from interface: Edge

Given a vertexId that represents one side of a relationship, get me the id of the other side.

Specified by:

getOtherVertexId in interface Edge

getVertices

public EdgeVertices getVertices(FetchHints fetchHints,
                                Authorizations authorizations)

Description copied from interface: Edge

Gets both in and out vertices of this edge.

Specified by:

getVertices in interface Edge

prepareMutation

public ExistingEdgeMutation prepareMutation()

Description copied from interface: Element

Prepares a mutation to allow changing multiple property values at the same time. This method is similar to Graph#prepareVertex(Visibility, Authorizations) in that it allows multiple properties to be changed and saved in a single mutation.

Specified by:

prepareMutation in interface Edge

Specified by:

prepareMutation in interface Element

Specified by:

prepareMutation in class InMemoryElement<InMemoryEdge>

Returns:

The mutation builder.
