Class JustificationsSupplier

java.lang.Object

org.optaplanner.constraint.streams.common.inliner.JustificationsSupplier

public final class JustificationsSupplier
extends Object

Allows to create justifications and indictments lazily if and only if constraint matches are enabled. Justification and indictment creation is performance expensive and constraint matches are typically disabled. So justifications and indictments are created lazily, outside of the typical hot path.
