Method Detail

edges

default java.util.Iterator<Edge> edges(Direction direction,
                                       java.lang.String... edgeLabels)

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.

getDegree

long getDegree(com.tinkerpop.blueprints.Direction direction,
               java.lang.String... labels)

Return the vertices adjacent to the vertex according to the provided direction and edge labels.

Parameters:

direction - the direction of the edges of the adjacent vertices

labels - the labels of the edges of the adjacent vertices

Returns:

an iterable of adjacent vertices

label

default java.lang.String label()

Gets the label for the vertex which helps categorize it. Not yet implemented.

Specified by:

label in interface Element

Throws:

java.lang.UnsupportedOperationException

property

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

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. NOT IMPLEMENTED YET

Specified by:

property in interface Vertex

setLabel

void setLabel(java.lang.String label)

Sets (and overrides) the label of this given vertex

vertices

default java.util.Iterator<Vertex> vertices(Direction direction,
                                            java.lang.String... edgeLabels)

Gets an Iterator of adjacent vertices.

Specified by:

vertices in interface Vertex

Parameters:

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

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