- - ### Constructor Detail

    - #### DeflateCompressorOutputStream

          public DeflateCompressorOutputStream(OutputStream outputStream)
                                        throws IOException

      Creates a Deflate compressed output stream with the default parameters.
      Parameters:
        `outputStream` - the stream to wrap
      Throws:
        `IOException` - on error

    - #### DeflateCompressorOutputStream

          public DeflateCompressorOutputStream(OutputStream outputStream,
                                       DeflateParameters parameters)
                                        throws IOException

      Creates a Deflate compressed output stream with the specified parameters.
      Parameters:
        `outputStream` - the stream to wrap
        `parameters` - the deflate parameters to apply
      Throws:
        `IOException` - on error

  - ### Method Detail

    - #### write

          public void write(int b)
                     throws IOException

      Specified by:
        `write` in class `OutputStream`
      Throws:
        `IOException`

    - #### write

          public void write(byte[] buf,
                   int off,
                   int len)
                     throws IOException

      Overrides:
        `write` in class `OutputStream`
      Throws:
        `IOException`

    - #### flush

          public void flush()
                     throws IOException

      Flushes the encoder and calls `outputStream.flush()`. All buffered pending data will then be decompressible from the output stream. Calling this function very often may increase the compressed file size a lot.
      Specified by:
        `flush` in interface `Flushable`
      Overrides:
        `flush` in class `OutputStream`
      Throws:
        `IOException`

    - #### finish

          public void finish()
                      throws IOException

      Finishes compression without closing the underlying stream.

      No more data can be written to this stream after finishing.

      Throws:
        `IOException` - on error

    - #### close

          public void close()
                     throws IOException

      Specified by:
        `close` in interface `Closeable`
      Specified by:
        `close` in interface `AutoCloseable`
      Overrides:
        `close` in class `OutputStream`
      Throws:
        `IOException`
