ScoreBounds

public ScoreBounds()

Use this constructor for the default bounds of negative and positive infinity

ScoreBounds

public ScoreBounds(int precision)

Use this constructor for the default bounds of negative and positive infinity It also allows precision to be set.

ScoreBounds

public ScoreBounds(java.lang.Double minPossibleScore,
                   java.lang.Double maxPossibleScore)

Use this constructor for providing starting values for an incremental update. Uses default precision.

Parameters:

minPossibleScore - starting rho for smallest possible score

maxPossibleScore - starting rho for largest possible score

ScoreBounds

public ScoreBounds(java.lang.Double minPossibleScore,
                   java.lang.Double maxPossibleScore,
                   int precision)

Use this constructor for providing starting values for an incremental update.

Parameters:

minPossibleScore - starting rho for smallest possible score

maxPossibleScore - starting rho for largest possible score

precision - amount of precision in score display
