Method Detail

print

public void print(MoneyPrintContext context,
                  java.lang.Appendable appendable,
                  BigMoney money)
           throws java.io.IOException

Description copied from interface: MoneyPrinter

Prints part of a monetary value to the output appendable.

The implementation determines what to append, which may be some or all of the data held in the BigMoney.

The context is not a thread-safe object and a new instance will be created for each print. The context must not be stored in an instance variable or shared with any other threads.

Specified by:

print in interface MoneyPrinter

Parameters:

context - the context being used, not null

appendable - the appendable to add to, not null

money - the money to print, not null

Throws:

java.io.IOException - if an IO exception occurs

parse

public void parse(MoneyParseContext context)

Description copied from interface: MoneyParser

Parses monetary information using a textual representation.

The text and parse index are stored in the context. The parsed data and updated index is also stored in the context.

Implementations should avoid throwing exceptions and use the error index in the context instead to record the problem. The context can be assumed to not be in error on entry to this method.

The context is not a thread-safe object and a new instance will be created for each parse. The context must not be stored in an instance variable or shared with any other threads.

Specified by:

parse in interface MoneyParser

Parameters:

context - the context to use and parse into, not null

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object
