Method Detail

values

public static final RoundingMode[] values()

Returns an array containing the constants of this enum type, in the order they're declared. This method may be used to iterate over the constants as follows:

for(RoundingMode c : RoundingMode.values())
        System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they're declared

valueOf

public static RoundingMode valueOf(java.lang.String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

java.lang.IllegalArgumentException - if this enum type has no constant with the specified name

validateFigures

public abstract ValidationResult validateFigures(Attribute attribute,
                                                 int figures)

Validates figures attribute.

Parameters:

attribute - attribute to be validated

figures - attribute's value to be validated

Returns:

result of validation

round

protected abstract java.math.BigDecimal round(double number,
                                              int figures)

Rounds given number for given number of figures.

Parameters:

number - number

figures - number of figures

Returns:

rounded number

isEqual

public boolean isEqual(double firstNumber,
                       double secondNumber,
                       int figures)

Returns true if given two numbers are equal after rounding; false otherwise.

Parameters:

firstNumber - first number to compare

secondNumber - second number to compare

figures - rounding figures

Returns:

true if given two numbers are equal after rounding; false otherwise

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Enum<RoundingMode>

parseRoundingMode

public static RoundingMode parseRoundingMode(java.lang.String roundingMode)

Parses string representation of RoundingMode.

Parameters:

roundingMode - string representation of RoundingMode

Returns:

parsed RoundingMode
