| 19 | * Provides a uniform interface to obtain a {@code BigMoney}. | |
| 20 | * <p> | |
| 21 | * When designing APIs, it is recommended to use {@code BigMoneyProvider} | |
| 22 | * in method signatures where possible to allow the widest possible use of the method. | |
| 23 | * Within Joda-Money, both {@code BigMoney} and {@code Money} implement | |
| 24 | * the provider interface. | |
| 25 | * <p> | |
| 26 | * Implementations of {@code BigMoneyProvider} may be mutable. | |
| 27 | * To minimise the risk of the value of the provider changing while processing, | |
| 28 | * any method that takes a {@code BigMoneyProvider} as a parameter should convert | |
| 29 | * it to a {@code BigMoney} immediately and use that directly from then on. | |
| 30 | * The method {@link BigMoney#of(BigMoneyProvider)} performs the conversion | |
| 31 | * safely with null checks and is recommended for this purpose. | |
| 32 | * <p> | |
| 33 | * This interface makes no guarantees about the immutability or | |
| 34 | * thread-safety of implementations. | |
