      org.mortbay.util.ByteArrayISO8859Writer

All Implemented Interfaces:

Closeable, Flushable, Appendable

public class ByteArrayISO8859Writer
extends Writer

Byte Array ISO 8859 writer. This class combines the features of a OutputStreamWriter for ISO8859 encoding with that of a ByteArrayOutputStream. It avoids many inefficiencies associated with these standard library classes. It has been optimized for standard ASCII characters.
