All Implemented Interfaces:

Collector<T>

public class SolutionSetUpdateOutputCollector<T>
extends Object
implements Collector<T>

A Collector to update the solution set of a workset iteration.

The records are written to a HashTable hash table to allow in-memory point updates.

Records will only be collected, if there is a match after probing the hash table. If the build side iterator is already positioned for the update, use SolutionSetFastUpdateOutputCollector to the save re-probing.
