Class UnicodeEscapeInputStreamReader

java.lang.Object
  java.io.Reader
      java.io.InputStreamReader
          ariba.util.io.UnicodeEscapeInputStreamReader

All Implemented Interfaces:

java.io.Closeable, java.lang.Readable

public class UnicodeEscapeInputStreamReader
extends java.io.InputStreamReader

UnicodeEscapeInputStreamReader is a special inputStreamWriter to read from the underlying input stream and convert the data into UnicodeEscaped (Ariba's internal encoding scheme) format. This is used internally by our stubgenerator, should not be used elsewhere.

Constructor Summary

UnicodeEscapeInputStreamReader(java.io.InputStream in)
Create an InputStreamReader that uses internal Ariba encoding.

UnicodeEscapeInputStreamReader(java.io.InputStream in, java.lang.String enc)
Constructor: we don't support this constructor.

Method Summary

void	close() Close the stream.
java.lang.String	getEncoding() Returns the canonical name of the character encoding being used by this stream.
int	read(char[] cbuf, int off, int len) Read characters into a portion of an array.
boolean	ready() Tell whether this stream is ready to be read.

Constructor Detail

UnicodeEscapeInputStreamReader

public UnicodeEscapeInputStreamReader(java.io.InputStream in)

Create an InputStreamReader that uses internal Ariba encoding.

Parameters:

in - An InputStream, must not be null.

UnicodeEscapeInputStreamReader

public UnicodeEscapeInputStreamReader(java.io.InputStream in,
                                      java.lang.String enc)
                               throws java.io.UnsupportedEncodingException

Constructor: we don't support this constructor. It will assert.

Parameters:

in - An InputStream

enc - The encoding

Throws:

java.io.UnsupportedEncodingException - If the named encoding is not supported

Method Detail

getEncoding

public java.lang.String getEncoding()

Returns the canonical name of the character encoding being used by this stream. Note that for this class, the Ariba internal UnicodeEscape encoding is used.

Overrides:

getEncoding in class java.io.InputStreamReader

Returns:

a String representing the encoding name.

read

public int read(char[] cbuf,
                int off,
                int len)
         throws java.io.IOException

Read characters into a portion of an array.

Overrides:

read in class java.io.InputStreamReader

Parameters:

cbuf - Destination buffer

off - Offset at which to start storing characters

len - Maximum number of characters to read

Returns:

The number of characters read, or -1 if the end of the stream has been reached

Throws:

java.io.IOException - If an I/O error occurs

ready

public boolean ready()
              throws java.io.IOException

Tell whether this stream is ready to be read. An InputStreamReader is ready if its input buffer is not empty, or if bytes are available to be read from the underlying byte stream.

Overrides:

ready in class java.io.InputStreamReader

Throws:

java.io.IOException - If an I/O error occurs

close

public void close()
           throws java.io.IOException

Close the stream.

Specified by:

close in interface java.io.Closeable

Overrides:

close in class java.io.InputStreamReader

Throws:

java.io.IOException - If an I/O error occurs
