addEdge(String label,
Vertex inVertex,

Add an outgoing edge to the vertex with provided label and edge properties as key/value pairs.
|

edges(Direction direction,
String... edgeLabels)
Gets an
Iterator of incident edges. |
<V> Iterator<VertexProperty<V>> |
properties(String... propertyKeys)
Get an
Iterator of properties where the propertyKeys is meant to be a filter on the available
keys. |
<V> VertexProperty<V> |
property(String key,
V value,
Object... keyValues)
Set the provided key to the provided value using default
VertexProperty.Cardinality for that key. |
<V> VertexProperty<V> |
property(VertexProperty.Cardinality cardinality,
String key,
V value,
Object... keyValues)
Create a new vertex property.

The default cardinality can be vendor defined and is usually tied to the graph schema.
