getMaxValue

public static <T extends Number & Comparable<T>> T getMaxValue(Class<?> klass)

longConverter

public static <T extends Number> Function<Long,T> longConverter(Class<?> klass)

bigDecimalConverter

public static <T extends Number>

calculateNewMin

public static <T extends Number & Comparable<T>> T calculateNewMin(@Nullable
 T curMin,
 @NotNull
 T newMax,
 int percentage)

Calculate a new minimum given the new maximum.

If the new maximum is less than the current minimum, returns a new minimum value that is less than the nex maximum by the specified percentage. Otherwise, returns the current minimum.

Type Parameters:

T - number type

Parameters:

curMin - current minimum

newMax - new maximum

percentage - to adjust by

Returns:

new minimum if current minimum is greater than the new maximum

calculateNewMax

public static <T extends Number & Comparable<T>> T calculateNewMax(@Nullable
 T curMax,
 @NotNull
 T newMin,
 int percentage)

Calculate a new maximum given the new minimum.

If the new minimum is greater than the current maximum, returns a new maximum value that is higher than the new minimum by the specified percentage. Otherwise, returns the current maximum.

Type Parameters:

T - number type

Parameters:

curMax - current maximum

newMin - new minimum

percentage - to adjust by

Returns:

new maximum if current maximum is less than the new minimum

calculateNewMinSize

public static int calculateNewMinSize(@Nullable
 @Nullable Integer curMin,
 Integer newMax)

calculateNewMaxSize

public static int calculateNewMaxSize(@Nullable
 @Nullable Integer curMax,
 Integer newMin)

sumDigits

public static int sumDigits(int num)
