Constructor Summary

BendableScoreDefinition(int hardLevelCount, int softLevelCount)

Method Summary

BendableScore	buildOptimisticBound(InitializingScoreTrend initializingScoreTrend, BendableScore score) Builds a Score which is equal or better than any other Score with more variables initialized (while the already variables don't change).
BendableScore	buildPessimisticBound(InitializingScoreTrend initializingScoreTrend, BendableScore score) Builds a Score which is equal or worse than any other Score with more variables initialized (while the already variables don't change).
BendableScoreHolder	buildScoreHolder(boolean constraintMatchEnabled) Used by DroolsScoreDirector.
BendableScore	createScore(int... scores)
int	getFeasibleLevelCount() Returns the number of levels of Score.toLevelNumbers().
int	getHardLevelCount()
int	getLevelCount() Returns the length of Score.toLevelNumbers() for every Score of this definition.
double	getRecursiveTimeGradientWeight()
Class<BendableScore>	getScoreClass() Returns the Class of the actual Score implementation
int	getSoftLevelCount()
BendableScore	parseScore(String scoreString) Parses the String and returns a Score.
void	setRecursiveTimeGradientWeight(double recursiveTimeGradientWeight) It's recommended to use a number which can be exactly represented as a double, such as 0.5, 0.25, 0.75, 0.125, ... but not 0.1, 0.2, ...
