Class BigMoney

  • All Implemented Interfaces:
    Serializable, Comparable<BigMoneyProvider>, BigMoneyProvider
    public final class BigMoney
extends Object
implements BigMoneyProvider, Comparable<BigMoneyProvider>, Serializable
    An amount of money with unrestricted decimal place precision.

    This class represents a quantity of money, stored as a BigDecimal amount in a single currency.

    Every currency has a certain standard number of decimal places. This is typically 2 (Euro, British Pound, US Dollar) but might be 0 (Japanese Yen), 1 (Vietnamese Dong) or 3 (Bahrain Dinar). The BigMoney class is not restricted to the standard decimal places and can represent an amount to any precision that a BigDecimal can represent.

    This class is immutable and thread-safe.

    • Method Detail

      • of

        public static BigMoney of​(CurrencyUnit currency,
                          BigDecimal amount)
        Obtains an instance of BigMoney from a BigDecimal.

        This allows you to create an instance with a specific currency and amount. The scale of the money will be that of the BigDecimal, with a minimum scale of zero.

        Parameters:
        currency - the currency, not null
        amount - the amount of money, not null
        Returns:
        the new instance, never null
        Throws:
        IllegalArgumentException - if an invalid BigDecimal subclass has been used

      • of

        public static BigMoney of​(CurrencyUnit currency,
                          double amount)
        Obtains an instance of BigMoney from a double using a well-defined conversion.

        This allows you to create an instance with a specific currency and amount.

        The amount is converted via BigDecimal.valueOf(double) which yields the most expected answer for most programming scenarios. Any double literal in code will be converted to exactly the same BigDecimal with the same scale. For example, the literal '1.425d' will be converted to '1.425'. The scale of the money will be that of the BigDecimal produced, with trailing zeroes stripped, and with a minimum scale of zero.

        Parameters:
        currency - the currency, not null
        amount - the amount of money, not null
        Returns:
        the new instance, never null

      • ofScale

        public static BigMoney ofScale​(CurrencyUnit currency,
                               BigDecimal amount,
                               int scale)
        Obtains an instance of BigMoney from a BigDecimal at a specific scale.

        This allows you to create an instance with a specific currency and amount. No rounding is performed on the amount, so it must have a scale less than or equal to the new scale. The result will have a minimum scale of zero.

        Parameters:
        currency - the currency, not null
        amount - the amount of money, not null
        scale - the scale to use, zero or positive
        Returns:
        the new instance, never null
        Throws:
        ArithmeticException - if the scale exceeds the currency scale

      • ofScale

        public static BigMoney ofScale​(CurrencyUnit currency,
                               BigDecimal amount,
                               int scale,
                               RoundingMode roundingMode)
        Obtains an instance of BigMoney from a double using a well-defined conversion, rounding as necessary.

        This allows you to create an instance with a specific currency and amount. If the amount has a scale in excess of the scale of the currency then the excess fractional digits are rounded using the rounding mode. The result will have a minimum scale of zero.

        Parameters:
        currency - the currency, not null
        amount - the amount of money, not null
        scale - the scale to use, zero or positive
        roundingMode - the rounding mode to use, not null
        Returns:
        the new instance, never null
        Throws:
        ArithmeticException - if the rounding fails

      • ofScale

        public static BigMoney ofScale​(CurrencyUnit currency,
                               long unscaledAmount,
                               int scale)
        Obtains an instance of BigMoney from a scaled amount.

        This allows you to create an instance with a specific currency, amount and scale. The amount is defined in terms of the specified scale. The result will have a minimum scale of zero.

        For example, ofScale(USD, 234, 2) creates the instance USD 2.34.

        Parameters:
        currency - the currency, not null
        unscaledAmount - the unscaled amount of money
        scale - the scale to use
        Returns:
        the new instance, never null

      • ofMajor

        public static BigMoney ofMajor​(CurrencyUnit currency,
                               long amountMajor)
        Obtains an instance of BigMoney from an amount in major units.

        This allows you to create an instance with a specific currency and amount. The scale of the money will be zero.

        The amount is a whole number only. Thus you can initialise the value 'USD 20', but not the value 'USD 20.32'. For example, ofMajor(USD, 25) creates the instance USD 25.

        Parameters:
        currency - the currency, not null
        amountMajor - the amount of money in the major division of the currency
        Returns:
        the new instance, never null

      • ofMinor

        public static BigMoney ofMinor​(CurrencyUnit currency,
                               long amountMinor)
        Obtains an instance of BigMoney from an amount in minor units.

        This allows you to create an instance with a specific currency and amount expressed in terms of the minor unit. The scale of the money will be that of the currency, such as 2 for USD or 0 for JPY.

        For example, if constructing US Dollars, the input to this method represents cents. Note that when a currency has zero decimal places, the major and minor units are the same. For example, ofMinor(USD, 2595) creates the instance USD 25.95.

        Parameters:
        currency - the currency, not null
        amountMinor - the amount of money in the minor division of the currency
        Returns:
        the new instance, never null

      • zero

        public static BigMoney zero​(CurrencyUnit currency)
