Constructors

Constructor and Description
HyperLogLog.Builder(double rsd) Deprecated. Use withRsd(double) instead. This builder's constructors did not match the (already themselves ambiguous) constructors of the HyperLogLog class, but there is no way to make them match without risking behavior changes downstream.

Constructor Detail

HyperLogLog.Builder

@Deprecated
public HyperLogLog.Builder(double rsd)

Deprecated. Use withRsd(double) instead. This builder's constructors did not match the (already themselves ambiguous) constructors of the HyperLogLog class, but there is no way to make them match without risking behavior changes downstream.

Uses the given RSD percentage to determine how many bytes the constructed HyperLogLog will use.
