public final class Money
extends Object
implements FastExternalizable, Comparable<Money>

Money

public Money(Currency currency,
 BigDecimal value)
      throws NumberFormatException

Will change the scale of the value to match the currency, but will not round.

Method Details

parseMoneyAmount

public static BigDecimal parseMoneyAmount(Locale locale,
 String symbol,
 String value)
                                   throws NumberFormatException

Parses a monetary amount with an optional symbol prefix. Trims, strips the prefix, trims, removes any commas.

TODO: A future version should be more locale-aware regarding assumption comma is used for group separator.

Parameters:

symbol - The optional currency prefix to strip (see CurrencyUtil.getSymbol(java.util.Currency, java.util.Locale))

value - The value to parse

Returns:

The monetary amount or null if empty

Throws:

NumberFormatException - when not a value amount after filtering

 Locale locale,
 String value)

equals

public boolean equals(Object o)

Equal when has same currency, value, and scale.

Overrides:

equals in class Object

hashCode

public int hashCode()

Overrides:

hashCode in class Object

compareTo

public int compareTo(Money other)

Sorts by currency code and then value.

Specified by:

compareTo in interface Comparable<Money>

               throws ArithmeticException

Throws:

ArithmeticException

getSerialVersionUID

public long getSerialVersionUID()

Description copied from interface: FastExternalizable

Gets the serialVersionUID for this object. Since FastExternalizable-aware containers are not special JVM constructs, they do not have access to the private and protected fields. It is assumed that two separate instances of the same class will always return the same serialVersionUID.

Specified by:

getSerialVersionUID in interface FastExternalizable

writeExternal

public void writeExternal(ObjectOutput out)
                   throws IOException

Specified by:

writeExternal in interface Externalizable

Throws:

IOException

readExternal

public void readExternal(ObjectInput in)
                  throws IOException,
ClassNotFoundException

Specified by:

readExternal in interface Externalizable

Throws:

IOException

ClassNotFoundException
