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.
