Method Detail

nodeMapping

NodeMapping nodeMapping()

nodeLabels

default java.util.Set<NodeLabel> nodeLabels(long nodeId)

Specified by:

nodeLabels in interface NodeMapping

availableNodeLabels

default java.util.Set<NodeLabel> availableNodeLabels()

Specified by:

availableNodeLabels in interface NodeMapping

isEmpty

default boolean isEmpty()

relationshipCount

long relationshipCount()

Returns:

returns the total number of relationships in the graph.

release

default void release()

Release all resources which are not part of the result or IdMapping

releaseTopology

default void releaseTopology()

Release only the topological data associated with that graph.

releaseProperties

default void releaseProperties()

Release only the properties associated with that graph.

isUndirected

boolean isUndirected()

hasRelationshipProperty

boolean hasRelationshipProperty()

canRelease

void canRelease(boolean canRelease)

intersection

default RelationshipIntersect intersection()

intersection

RelationshipIntersect intersection(long maxDegree)

concurrentCopy

default Graph concurrentCopy()

Specified by:

concurrentCopy in interface RelationshipIterator

Returns:

a copy of this iterator that reuses new cursors internally, so that iterations happen independent from other iterations.
