Method Detail

exists

public CompletableFuture<Boolean> exists()

Description copied from interface: ArangoGraphAsync

Checks whether the graph exists

Specified by:

exists in interface ArangoGraphAsync

Returns:

true if the graph exists, otherwise false

create

public CompletableFuture<GraphEntity> create(Collection<EdgeDefinition> edgeDefinitions)

Description copied from interface: ArangoGraphAsync

Creates the graph in the graph module. The creation of a graph requires the name of the graph and a definition of its edges.

Specified by:

create in interface ArangoGraphAsync

Parameters:

edgeDefinitions - An array of definitions for the edge

Returns:

information about the graph

See Also:

API Documentation

createGraph

public CompletableFuture<GraphEntity> createGraph(Collection<EdgeDefinition> edgeDefinitions,
                                                  GraphCreateOptions options)

Description copied from interface: ArangoGraphAsync

Creates the graph in the graph module. The creation of a graph requires the name of the graph and a definition of its edges.

Specified by:

createGraph in interface ArangoGraphAsync

Parameters:

edgeDefinitions - An array of definitions for the edge

options - Additional options, can be null

Returns:

information about the graph

API Documentation

drop

public CompletableFuture<Void> drop()

Description copied from interface: ArangoGraphAsync

Delete an existing graph

Specified by:

drop in interface ArangoGraphAsync

Returns:

void

See Also:

API Documentation

drop

public CompletableFuture<Void> drop(boolean dropCollections)

Description copied from interface: ArangoGraphAsync

Delete an existing graph including

Specified by:

drop in interface ArangoGraphAsync

Parameters:

dropCollections - Drop collections of this graph as well. Collections will only be dropped if they are not used in other graphs.

Returns:

void

See Also:

API Documentation

getInfo

public CompletableFuture<GraphEntity> getInfo()

Description copied from interface: ArangoGraphAsync

Get a graph from the graph module

Specified by:

getInfo in interface ArangoGraphAsync

Returns:

the definition content of this graph

See Also:

API Documentation

getVertexCollections

public CompletableFuture<Collection<String>> getVertexCollections()

Description copied from interface: ArangoGraphAsync
