Package ai.timefold.solver.core.impl.bavet.common

Class RecordAndReplayPropagator<Tuple_ extends Tuple>

java.lang.Object

ai.timefold.solver.core.impl.bavet.common.RecordAndReplayPropagator<Tuple_>

Type Parameters:

Tuple_ -

All Implemented Interfaces:

Propagator

@NullMarked
public final class RecordAndReplayPropagator<Tuple_ extends Tuple>
extends Object
implements Propagator

The implementation records the tuples each object affects inside an internal NodeNetwork and replays them on update. Used by AbstractPrecomputeNode to precompute constraint streams.
