build

public SingleTypeRelationships build(java.util.Optional<AdjacencyCompressor.ValueMapper> mapper,
                                     java.util.Optional<java.util.function.LongConsumer> drainCountConsumer)

Parameters:

mapper - A mapper to transform values before compressing them. Implementations must be thread-safe.

drainCountConsumer - A consumer which is called once a ChunkedAdjacencyLists has been drained and its contents are written to the adjacency list. The consumer receives the number of relationships that have been written. Implementations must be thread-safe.
