```
public final class Currency
extends Object
implements Comparable<Currency>, Serializable
```
A unit of currency.
This class represents a unit of currency such as the British Pound, Euro or US Dollar. The currency is represented by a three letter code, intended to be ISO-4217.
It is recommended to define currencies in advance using the Currency.ini file. Standard configuration includes many commonly used currencies.
Only currencies listed in configuration will be returned by getAvailableCurrencies(). If a currency is requested that is not defined in configuration, it will still be created, however it will have the default value of zero for the minor units and 'USD' for the triangulation currency.
This class is immutable and thread-safe.

- Method Detail
  - getAvailableCurrencies
```
public static Set<Currency> getAvailableCurrencies()
```
    Obtains the set of configured currencies.
    This contains all the currencies that have been defined in configuration. Any currency instances that have been dynamically created are not included.
    
    Returns:
    
    an immutable set containing all registered currencies
  - of
```
public static Currency of(String currencyCode)
```
    Obtains an instance for the specified ISO-4217 three letter currency code.
    A currency is uniquely identified by ISO-4217 three letter code. Currencies should be defined in configuration before they can be used. If the requested currency is not defined in configuration, it will still be created, however it will have the default value of zero for the minor units and 'USD' for the triangulation currency.
    
    Parameters:
    
    currencyCode - the three letter currency code, ASCII and upper case
    
    Returns:
    
    the singleton instance
    
    Throws:
    
    IllegalArgumentException - if the currency code is invalid
  - parse
```
public static Currency parse(String currencyCode)
```
    Parses a string to obtain a Currency.
    The parse is identical to of(String) except that it will convert letters to upper case first. If the requested currency is not defined in configuration, it will still be created, however it will have the default value of zero for the minor units and 'USD' for the triangulation currency.
    
    Parameters:
    
    currencyCode - the three letter currency code, ASCII
    
    Returns:
    
    the singleton instance
    
    Throws:
    
    IllegalArgumentException - if the currency code is invalid
  - getCode
```
public String getCode()
```
    Gets the three letter ISO code.
    
    Returns:
    
    the three letter ISO code
  - getMinorUnitDigits
```
public int getMinorUnitDigits()
```
    Gets the number of digits in the minor unit.
    For example, 'USD' will return 2, indicating that there are two digits, corresponding to cents in the dollar.
    
    Returns:
    
    the number of fraction digits
  - getTriangulationCurrency
```
public Currency getTriangulationCurrency()
```
    Gets the preferred triangulation currency.
    When obtaining a market quote for a currency, the triangulation currency is used if no direct rate can be found. For example, there is no direct rate for 'CZK/SGD'. Instead 'CZK' might be defined to triangulate via 'EUR' and 'SGD' with 'USD'. Since the three rates, 'CZK/EUR', 'EUR/USD' and 'USD/SGD' can be obtained, a rate can be determined for 'CZK/SGD'. Note that most currencies triangulate via 'USD'.
    
    Returns:
    
    the triangulation currency
  - roundMinorUnits
```
public double roundMinorUnits(double amount)
```
    Rounds the specified amount according to the minor units.
    For example, 'USD' has 2 minor digits, so 63.347 will be rounded to 63.35.
    
    Parameters:
    
    amount - the amount to round
    
    Returns:
    
    the rounded amount
  - roundMinorUnits
```
public BigDecimal roundMinorUnits(BigDecimal amount)
```
    Rounds the specified amount according to the minor units.
    For example, 'USD' has 2 minor digits, so 63.347 will be rounded to 63.35.
    
    Parameters:
    
    amount - the amount to round
    
    Returns:
    
    the rounded amount
  - roundMinorUnits
```
public Decimal roundMinorUnits(Decimal amount)
```
    Rounds the specified amount according to the minor units.
    For example, 'USD' has 2 minor digits, so 63.347 will be rounded to 63.35.
    
    Parameters:
    
    amount - the amount to round
    
    Returns:
    
    the rounded amount
  - compareTo
```
public int compareTo(Currency other)
```
    Compares this currency to another.
    The comparison sorts alphabetically by the three letter currency code.
    
    Specified by:
    
    compareTo in interface Comparable<Currency>
    
    Parameters:
    
    other - the other currency
    
    Returns:
    
    negative if less, zero if equal, positive if greater
  - equals
```
public boolean equals(Object obj)
```
    Checks if this currency equals another currency.
    The comparison checks the three letter currency code.
    
    Overrides:
    
    equals in class Object
    
    Parameters:
    
    obj - the other currency, null returns false
    
    Returns:
    
    true if equal
  - hashCode
```
public int hashCode()
```
    Returns a suitable hash code for the currency.
    
    Overrides:
    
    hashCode in class Object
    
    Returns:
    
    the hash code
  - toString
```
public String toString()
```
    Returns a string representation of the currency, which is the three letter code.
    
    Overrides:
    
    toString in class Object
    
    Returns:
    
    the three letter currency code
