Method Summary

Modifier and Type	Method and Description
static <A,B> ParamAndField<A,B>	pickBest(FieldScoreProducer<A,B> producer, A[] params, Random random) Pick a random best FieldScore when scoring. NOTE: Because an underlying HashMap is used, to guarantee the same randomization, both the A and B classes must implement hashCode properly! NOTE: When scoring multiple parameters, the second must exceed in score in order to be chosen, if all scores are equal the first parameter will be selected.
static <A,B> ParamAndField<A,B>	pickBest(FieldScoreProducer<A,B> producer, A params, Random random) Pick a random best FieldScore when scoring. NOTE: Because an underlying HashMap is used, to guarantee the same randomization, the B parameter must implement hashCode properly!

Method Detail

pickBest

public static <A,B> ParamAndField<A,B> pickBest(Map<A,FieldScores<A,B>> scores,
                                                Random random)

pickBest

public static <A,B> ParamAndField<A,B> pickBest(FieldScoreProducer<A,B> producer,
                                                A params,
                                                Random random)

Pick a random best FieldScore when scoring.
NOTE: Because an underlying HashMap is used, to guarantee the same randomization, the B parameter must implement hashCode properly!

Parameters:

producer - The producer for the FieldScores

params - The parameter to pass the producer

random - Random object to use

Returns:

A randomly selected best tuple of the parameter and the FieldScore for the chosen field.

pickBest

public static <A,B> ParamAndField<A,B> pickBest(FieldScoreProducer<A,B> producer,
                                                A[] params,
                                                Random random)

Pick a random best FieldScore when scoring.
NOTE: Because an underlying HashMap is used, to guarantee the same randomization, both the A and B classes must implement hashCode properly!
NOTE: When scoring multiple parameters, the second must exceed in score in order to be chosen, if all scores are equal the first parameter will be selected.

Parameters:

producer - The producer for the FieldScores

params - The parameters to pass the producer

random - Random object to use

Returns:

A randomly selected best tuple of FieldScore for the chosen field, connected to the parameter that produced the best score.
