LazyIdMapBuilder

public LazyIdMapBuilder(int concurrency,
                        boolean hasLabelInformation,
                        boolean hasProperties,
                        org.neo4j.gds.api.PropertyState propertyState)

Method Detail

prepareForFlush

public void prepareForFlush()

addNode

public long addNode(long nodeId,
                    NodeLabelToken nodeLabels)

addNodeWithProperties

public long addNodeWithProperties(long nodeId,
                                  PropertyValues properties,
                                  NodeLabelToken nodeLabels)

toMappedNodeId

public long toMappedNodeId(long originalNodeId)

Description copied from interface: PartialIdMap

Maps an original node id to a mapped node id. In case of nested id maps, the mapped node id is always in the space of the innermost mapping.

Specified by:

toMappedNodeId in interface PartialIdMap

Parameters:

originalNodeId - must be smaller or equal to the id returned by IdMap.highestOriginalId()

rootNodeCount

public java.util.OptionalLong rootNodeCount()

Description copied from interface: PartialIdMap

Number of mapped node ids in the root mapping. This is necessary for nested (filtered) id mappings.

Specified by:

rootNodeCount in interface PartialIdMap

build

public LazyIdMapBuilder.HighLimitIdMapAndProperties build()
