public java.util.List<Relationships> buildAll()

buildAll

public java.util.List<Relationships> buildAll(java.util.Optional<AdjacencyCompressor.ValueMapper> mapper,

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.
