Method Detail

gt

public static <T> scala.Function1<T,Object> gt(double lowerBound)

Check if value > lowerBound

gtEq

public static <T> scala.Function1<T,Object> gtEq(double lowerBound)

Check if value >= lowerBound

lt

public static <T> scala.Function1<T,Object> lt(double upperBound)

Check if value < upperBound

ltEq

public static <T> scala.Function1<T,Object> ltEq(double upperBound)

Check if value <= upperBound

inRange

public static <T> scala.Function1<T,Object> inRange(double lowerBound,
                                                    double upperBound,
                                                    boolean lowerInclusive,
                                                    boolean upperInclusive)

Check for value in range lowerBound to upperBound.

Parameters:

lowerInclusive - If true, check for value >= lowerBound. If false, check for value > lowerBound.

upperInclusive - If true, check for value <= upperBound. If false, check for value < upperBound.

lowerBound - (undocumented)

upperBound - (undocumented)

Returns:

(undocumented)

inRange

public static <T> scala.Function1<T,Object> inRange(double lowerBound,
