Interface BigMoneyProvider

  • All Known Implementing Classes:
    BigMoney, Money

    public interface BigMoneyProvider
    Provides a uniform interface to obtain a BigMoney.

    This interface provides an abstraction over Money and BigMoney. In general, applications should use the concrete types, not this interface. However, utilities and frameworks may choose to make use of this abstraction.

    Implementations of BigMoneyProvider may be mutable. To minimise the risk of the value of the provider changing while processing, any method that takes a BigMoneyProvider as a parameter should convert it to a BigMoney immediately and use that directly from then on. The method BigMoney.of(BigMoneyProvider) performs the conversion safely with null checks and is recommended for this purpose.

    This interface makes no guarantees about the immutability or thread-safety of implementations.

    • Method Detail

      • toBigMoney

        BigMoney toBigMoney()
        Returns a BigMoney instance equivalent to the value of this object.

        It is recommended that BigMoney.of(BigMoneyProvider) is used in preference to calling this method directly. It is also recommended that the converted BigMoney is cached in a local variable instead of performing the conversion multiple times.

        Returns:
        the converted money instance, never null
        Throws:
        java.lang.RuntimeException - if conversion is not possible
