          ariba.util.io.UnicodeEscapeOutputStreamWriter

All Implemented Interfaces:

Closeable, Flushable, Appendable

public class UnicodeEscapeOutputStreamWriter
extends OutputStreamWriter

UnicodeEscapeOutputStreamWriter is a special outputStreamWriter to write UnicodeEscaped (Ariba's internal encoding scheme) data to the underlying output stream. This is used internally by our JavaFile class, with the underlying output stream being a FileOutputStream.

Constructor Summary

UnicodeEscapeOutputStreamWriter(OutputStream out)
Create an OutputStreamWriter that uses Ariba internal encoding scheme.

UnicodeEscapeOutputStreamWriter(OutputStream out, String enc)
Create an OutputStreamWriter that uses the named character encoding.

Method Summary

void	close() Close the stream.
void	flush() Flush remaining data to the underlying output stream.
String	getEncoding() Returns the canonical name of the character encoding being used by this stream.
void	write(char[] cbuf, int off, int len) Write a portion of an array of characters.

Constructor Detail

UnicodeEscapeOutputStreamWriter

public UnicodeEscapeOutputStreamWriter(OutputStream out,
                                       String enc)
                                throws UnsupportedEncodingException

Create an OutputStreamWriter that uses the named character encoding. We don't support this constructor because this class only uses the Ariba internal encoding. We will assert.

Parameters:

out - An OutputStream

enc - The encoding

Throws:

UnsupportedEncodingException - If the named encoding is not supported

UnicodeEscapeOutputStreamWriter

public UnicodeEscapeOutputStreamWriter(OutputStream out)

Create an OutputStreamWriter that uses Ariba internal encoding scheme.

Parameters:

out - An OutputStream, must not be null.

Method Detail

getEncoding

public String getEncoding()

Returns the canonical name of the character encoding being used by this stream.

Overrides:

getEncoding in class OutputStreamWriter

Returns:

a String representing the encoding name

write

public void write(char[] cbuf,
                  int off,
                  int len)
           throws IOException

Write a portion of an array of characters.

Overrides:

write in class OutputStreamWriter

Parameters:

cbuf - Buffer of characters

off - Offset from which to start writing characters

len - Number of characters to write

Throws:

IOException - If an I/O error occurs

flush

public void flush()
           throws IOException

Flush remaining data to the underlying output stream.

Specified by:

flush in interface Flushable

Overrides:

flush in class OutputStreamWriter

Throws:

IOException

close

public void close()
           throws IOException

Close the stream. Note that we do not call the super class's close method because they call their own flush, and we don't want to flush our data twice.

Specified by:

close in interface Closeable

Overrides:

close in class OutputStreamWriter

Throws:

IOException - If an I/O error occurs
