Constructor Detail

• WriterStream

  public WriterStream(java.io.Writer w)

  Create a stream that writes to a writer.

  Parameters:

  w - the writer

• WriterStream

  public WriterStream(java.io.Writer w,
                      java.lang.String charsetName)

  Create a stream that writes to a writer.

  Parameters:

  w - the writer

  charsetName - name of encoding to be used when decode byte stream (instead of default one)

Method Detail

• flush

  public void flush()
             throws java.io.IOException

  Flush the stream.

  Specified by:

  flush in interface java.io.Flushable

  Overrides:

  flush in class java.io.OutputStream

  Throws:

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

• close

  public void close()
             throws java.io.IOException

  We override default implementation to write last characters, which could be lost in buffer otherwise.

  Specified by:

  close in interface java.io.Closeable

  Specified by:

  close in interface java.lang.AutoCloseable

  Overrides:

  close in class java.io.OutputStream

  Throws:

  java.io.IOException

• write

  public void write(int b)
             throws java.io.IOException

  OutputStream's implementation. Our goal is to convert encoded byte stream form OutputStream to char stream, which can be written using specified writer. We perform this by collecting bytes in buffer and checking with PERIOD_SIZE interval if this buffer represents some char sequence. If so, we write to writer all chars, except last one. We don't write last char, because there still not enough bytes could be collected for it.

  Specified by:

  write in class java.io.OutputStream

  Parameters:

  b - next byte from OutputStream to write.

  Throws:

  java.io.IOException
