Method Detail

at

public static GlobalGraphOperations at(GraphDatabaseService db)

Get a GlobalGraphOperations for the given db.

Parameters:

db - the GraphDatabaseService to get global operations for.

Returns:

a GlobalGraphOperations for the given db.

getAllNodes

public Iterable<Node> getAllNodes()

Returns all nodes in the graph.

Returns:

all nodes in the graph.

getAllRelationships

public Iterable<Relationship> getAllRelationships()

Returns all relationships in the graph.

Returns:

all relationships in the graph.

getAllRelationshipTypes

public Iterable<RelationshipType> getAllRelationshipTypes()

Returns all relationship types currently in the underlying store. Relationship types are added to the underlying store the first time they are used in a successfully committed node.createRelationshipTo(...). Note that this method is guaranteed to return all known relationship types, but it does not guarantee that it won't return more than that (e.g. it can return "historic" relationship types that no longer have any relationships in the node space).

Returns:

all relationship types in the underlying store

getAllNodesWithLabel

public ResourceIterable<Node> getAllNodesWithLabel(Label label)

Returns all nodes with a specific label.

Parameters:

label - the Label to return nodes for.

Returns:

an Iterable containing nodes with a specific label.
