Method Details

isOutOfRange

public static boolean isOutOfRange(Numeral numeral,
 NumeralType type)

Parameters:

numeral - Numeral to be checked

type - type to be checked

Returns:

true if the specified Numeral is outside the allowed range of the type

Throws:

NullPointerException - if the specified type is null or if the Numeral returns null for Numeral.getType()

IllegalArgumentException - if the specified type is not null or if the Numeral does not return null for Numeral.getType(), but the value is not recognised as any of the elements of NumeralType. This should never happen

isOutOfIntRange

public static boolean isOutOfIntRange(Numeral numeral)

Parameters:

numeral - Numeral to be checked

Returns:

true if the specified Numeral is smaller than Integer.MIN_VALUE or greater than Integer.MAX_VALUE

Throws:

NullPointerException - if the Numeral returns null for Numeral.getType()

IllegalArgumentException - if the Numeral does not return null for Numeral.getType(), but the value is not recognised as any of the elements of NumeralType. This should never happen

isOutOfLongRange

public static boolean isOutOfLongRange(Numeral numeral)

Parameters:

numeral - Numeral to be checked

Returns:

true if the specified Numeral is smaller than Long.MIN_VALUE or greater than Long.MAX_VALUE

Throws:

NullPointerException - if the Numeral returns null for Numeral.getType()

IllegalArgumentException - if the Numeral does not return null for Numeral.getType(), but the value is not recognised as any of the elements of NumeralType. This should never happen

isOutOfFloatRange

public static boolean isOutOfFloatRange(Numeral numeral)

Parameters:

numeral - Numeral to be checked

Returns:

true if the specified Numeral is smaller than -Float.MAX_VALUE or greater than Float.MAX_VALUE

NullPointerException - if the Numeral returns null for Numeral.getType()

IllegalArgumentException - if the Numeral does not return null for Numeral.getType(), but the value is not recognised as any of the elements of NumeralType. This should never happen

isOutOfDoubleRange

public static boolean isOutOfDoubleRange(Numeral numeral)

Parameters:

numeral - Numeral to be checked

Returns:

true if the specified Numeral is smaller than -Double.MAX_VALUE or greater than Double.MAX_VALUE
