com.google.ortools.constraintsolver.LocalSearchFilterManager

public class LocalSearchFilterManager
extends BaseObject

Filter manager: when a move is made, filters are executed to decide whether
the solution is feasible and compute parts of the new cost. This class
schedules filter execution and composes costs as a sum.
