Constructor Detail

CSRGraphAdapter

public CSRGraphAdapter(CSRGraph graph)

Method Detail

concurrentCopy

public CSRGraph concurrentCopy()

Specified by:

concurrentCopy in interface CSRGraph

Specified by:

concurrentCopy in interface Graph

Specified by:

concurrentCopy in interface RelationshipIterator

Returns:

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

relationshipTopologies

public java.util.Map<org.neo4j.gds.RelationshipType,Topology> relationshipTopologies()

Specified by:

relationshipTopologies in interface CSRGraph

addNodeLabel

public void addNodeLabel(org.neo4j.gds.NodeLabel nodeLabel)

Description copied from interface: IdMap

Adds new node label to the available node labels. The labels is not assigned to any nodes at this point.

Specified by:

addNodeLabel in interface IdMap

Overrides:

addNodeLabel in class GraphAdapter

Parameters:

nodeLabel - the node label to add

addNodeIdToLabel

public void addNodeIdToLabel(long nodeId,
                             org.neo4j.gds.NodeLabel nodeLabel)

Description copied from interface: IdMap

Assigns a node to the given node label.

Specified by:

addNodeIdToLabel in interface IdMap

Overrides:

addNodeIdToLabel in class GraphAdapter

Parameters:

nodeId - the node id to assign

nodeLabel - the node label to which the node will be assigned to
