Constructor Detail

• UTF8Reader

  public UTF8Reader(java.io.InputStream inputStream,
            int size)

  Constructs a UTF-8 reader from the specified input stream, buffer size and MessageFormatter.

  Parameters:

  inputStream - The input stream.

  size - The initial buffer size.

Method Detail

• read

  public int read()
           throws java.io.IOException

  Read a single character. This method will block until a character is available, an I/O error occurs, or the end of the stream is reached.

  Subclasses that intend to support efficient single-character input should override this method.

  Overrides:

  read in class java.io.Reader

  Returns:

  The character read, as an integer in the range 0 to 16383 (0x00-0xffff), or -1 if the end of the stream has been reached

  Throws:

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

• read

  public int read(char[] ch,
         int offset,
         int length)
           throws java.io.IOException

  Read characters into a portion of an array. This method will block until some input is available, an I/O error occurs, or the end of the stream is reached.

  Specified by:

  read in class java.io.Reader

  Parameters:

  ch - Destination buffer

  offset - Offset at which to start storing characters

  length - 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

• skip

  public long skip(long n)
            throws java.io.IOException

  Skip characters. This method will block until some characters are available, an I/O error occurs, or the end of the stream is reached.

  Overrides:

  skip in class java.io.Reader

  Parameters:

  n - The number of characters to skip

  Returns:

  The number of characters actually skipped

  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.

  Overrides:

  ready in class java.io.Reader

  Returns:

  True if the next read() is guaranteed not to block for input, false otherwise. Note that returning false does not guarantee that the next read will block.

  Throws:

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

• markSupported

  public boolean markSupported()

  Tell whether this stream supports the mark() operation.

  Overrides:

  markSupported in class java.io.Reader

• mark

  public void mark(int readAheadLimit)
            throws java.io.IOException

  Mark the present position in the stream. Subsequent calls to reset() will attempt to reposition the stream to this point. Not all character-input streams support the mark() operation.

  Overrides:

  mark in class java.io.Reader

  Parameters:

  readAheadLimit - Limit on the number of characters that may be read while still preserving the mark. After reading this many characters, attempting to reset the stream may fail.

  Throws:

  java.io.IOException - If the stream does not support mark(), or if some other I/O error occurs

• reset

  public void reset()
             throws java.io.IOException

  Reset the stream. If the stream has been marked, then attempt to reposition it at the mark. If the stream has not been marked, then attempt to reset it in some way appropriate to the particular stream, for example by repositioning it to its starting point. Not all character-input streams support the reset() operation, and some support reset() without supporting mark().

  Overrides:

  reset in class java.io.Reader

  Throws:

  java.io.IOException - If the stream has not been marked, or if the mark has been invalidated, or if the stream does not support reset(), or if some other I/O error occurs

• close

  public void close()
             throws java.io.IOException

  Close the stream. Once a stream has been closed, further read(), ready(), mark(), or reset() invocations will throw an IOException. Closing a previously-closed stream, however, has no effect.

  Specified by:

  close in interface java.io.Closeable

  Specified by:

  close in interface java.lang.AutoCloseable

  Specified by:

  close in class java.io.Reader

  Throws:

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