ArangoDB arango = new ArangoDB.Builder().build();
ArangoDatabase db = arango.db("myDB");
ArangoGraph graph = db.graph("some-graph");

ArangoVertexCollection collection = graph.vertexCollection("some-vertex-collection");
```

## ArangoGraph.getVertexCollections

`ArangoGraph.getVertexCollections() : Collection<String>`

Fetches all vertex collections from the graph and returns a list of collection names.

**Examples**

```Java
ArangoDB arango = new ArangoDB.Builder().build();
ArangoDatabase db = arango.db("myDB");
ArangoGraph graph = db.graph("some-graph");

Collection<String> collections = graph.getVertexCollections();
```

## ArangoGraph.addVertexCollection

`ArangoGraph.addVertexCollection(String name) : GraphEntity`

Adds a vertex collection to the set of collections of the graph.
If the collection does not exist, it will be created.

**Arguments**
