24.47 java.io.OutputStreamWriter (JDK 1.1)

This class is a character output stream that uses a byte output stream as the destination for its data: when characters are written to an OutputStreamWriter, it translates them into bytes according to a particular locale- and/or platform-specific character encoding, and writes those bytes to the specified OutputStream. This is a very important internationalization feature in Java 1.1.

When you create an OutputStreamWriter, you specify the OutputStream to which it writes bytes, and you optionally specify the name of the character encoding that should be used to convert characters to bytes. If you do not specify an encoding name, the OutputStreamWriter uses the default encoding of the default locale, which is usually the correct thing to do.

OutputStreamWriter supports the usual Writer methods. It also has a getEncoding() method which returns the name of the encoding being used to convert characters to bytes.

public class OutputStreamWriter extends Writer {
    // Public Constructors
            public OutputStreamWriter(OutputStream out, String enc) throws UnsupportedEncodingException;
            public OutputStreamWriter(OutputStream out);
    // Public Instance Methods
            public void close() throws IOException;  // Defines Writer
            public void flush() throws IOException;  // Defines Writer
            public String getEncoding();
            public void write(int c) throws IOException;  // Overrides Writer
            public void write(char[] cbuf, int off, int len) throws IOException;  // Defines Writer
            public void write(String str, int off, int len) throws IOException;  // Overrides Writer
}
